There are none except for the fact if the if the input signal has variations in value, with no filtering, the digital readouts can become a guess to read.
Analog meters will average these variations as a wiggle of the needle so that the reading changes in a slower manner which is easier to read.
Electronics have greatly evolved over the years and the current trend is towards digital being preferred by many. The digital instrument tones are far more accurate than analog, and need less maintenance and regular tuning, in fact no tuning at all, ever. Sounds that are digitally sampled have all of the harmonics of each note in the sample being heard, a feat that analog electronics cannot duplicate.

How are digital aerials different from analog ones?
Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.

What are the advantages of digital modulation over analog modulation?
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation
What is the difference between analog and digital data transmission?
This is essentially the same question as the difference between analog and digital. With analog electronics a voltage is used to represent (or to be an analogy for) some physical attribute in the real world. So for an analog transmission, at its simplest, a sound signal (say) is converted to a voltage, the voltage sent down a cable, then at the other end the voltage converted back into sound with a loudspeaker. With a digital system, the physicial attribute is measured and sent as a series of numbers, the numbers being converted to binary. For a digital transmission, the sound signal is converted to a series of numbers, sent as binary, and converted back to a sound signal at the other end. The advantages of digital is that it makes multiplexing much easier - making it easier to put many signals down the same physical cable. It also makes compressing the signal much easier - this is particularly effective for digital television transmission; 30-40 digital channels can be sent over the same bandwidth as 4 or 5 uncompressed analog channels. Also, digital is much more resiliant against noise - the digital receiver has to make a decision about each bit - is it there or not; noise can be pretty extreme before this becomes impossible, with analog, once noise is added its very difficult to remove it. The historical disadvantage of digital is that digital encoding and decoding equipment was expensive compared with the analog. Over the last 10 years or so, digital electronics has become much cheaper and more powerful.
What are the advantages of digital communications over analog communication?
Using analogue communication from a digital interface requires some kind of converter to convert your digital data into analogue before it can be sent. This data needs to be converted back into digital by the receiver. Hence a larger amount of work needs to be done. eg: the VGA cable used to connect a PC to a screen is a analogue cable. So all the video signals that are sent out by your PC are converted to analogue first. Hence there is a larger amount of work done. There is also a chance of data being lost during this conversion. If the source signal and the output signal are digital, then there is no conversion required and resulting work required is less. This also means that the receiver doesn't need to convert this data. Hence work done is less and data loss in conversion is also minimal. Although transmitting digital data over long distances also results in some amount of loss. eg: video signals transmitted through DVI or HDMI cables are purely digital. A PC or Blu-Ray player connected to a digital screen using any of the above interfaces doesn't need to convert the signal before sending it. Hence data loss is minimal and resulting picture is sharper and accurate.
What are the advantages of analog multimeter over digital multimeter?
The main advantage of a digital multimeter over an analog multimeter is their accuracy.AnswerDigital instruments are not necessarily more accurate than analogue instruments (although they often are), but they are far more robust and, usually, far easier to read without error. A digital multimeter has no moving parts and is unaffected by gravity, so they can be used at any angle, whereas analogue instruments needed to be placed on horizontal surfaces and not subjected to vibration.
What are the advantages of a digital radio over an analog radio?
The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.
What are the characteristics of digital transmission over analog?
Error can be easily detected in digital.
What are the advantages of transducers over nonelectrical measuring instruments?
Using your terminology, there are three types of instruments. Non-electrical instruments. example Pressure gage that is simply a dial mounted to measure pressure in a hose. Electrical instruments can be sub-divided into two types: analog and digital. Analog Electrical instruments are instruments that are operated with an electrical signal. The gage measures the change in resistance or impedance that correlates to a value of the parameter. Example: Pressure gage in an aicraft cockpit will be wired to a pressure transducer in the back of the aircraft. The electrical signal is processed by a computer that correlates the output to the analog dial. Digital Electrical instruments are instruments that send a digitized values for display. The transducers for this type system will transmit values in digital format or either a On/Off or 0/1 value. Example: A digital pressure system will convert the pressure into a digital value. The computer can use the digital value to display on a computer monitor either as a numeric value or a graphic display such as a colored band. The advantage of digital instruments is that is allows transmitting more data and information to computers and then be shared with different applications and displays. Whereas an analog system has limitations of accuracy of the data.
What is good about baby monitors?
Digital baby monitors have one main advantage over analog monitors. Digital monitors are encrypted so others cannot snoop, while analog monitor signals are not encrypted. Much higher price is the main disadvantage.

What are the advantages of digital stereo plotter over the analog type?
Digital stereo plotter is more accurate than the analog one in producing maps.

What are the disadvantages of having an analog watch?
The advantages of an analog watch over a digital watch are that analog watches can be more durable in some facets, than a digital one. Many watch enthusiasts also feel that analog watches are more aesthetically pleasing than digital watches.
Does a digital signal travel farther than an analog signal?
You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
What is a modem's function?
To transceive digital data over analog media.
What are the advantages of digital modulation over analog modulation?
