An analog or analogue signal is any continuous signal for which the time varying feature of the signal is a representation in respect to other time varying quantity, i.e., analogous to another time varying signal.
Any information may be conveyed by an analog signal often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure, and is achieved using a transducer.
So, Analog signal is a medium to send information over distance ,the information cane be anything. The main disadvantage of Analog signals is they have larger noise .
Alternating Current is defined as the behavior of Electric charge. Alternating Current is the movement of Electric current which is periodic and attains both positive and reverse direction (positive and negative) in its propagation whereas Direct Current only attains itself in one direction i.e positive cycle only.
So,the difference is...Analog is the type of signals whereas Alternating is a behavior of Electric charge on its movement.

What is the difference between analog and digital altimeter?
Analog is displayed in a clock like instrument digital is shoun in numbers
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What is the difference between microcontroller and psoc microcontroller?
Psoc includes the analog and digital component where else in controller only digital. :P
Difference between laplace transform and z transform?
the difference is the "S" and "Z" parameters. S used for analog computation while Z for digital processing. basically Z is the digital approximation of the analog frequency domain signal. Z=exp(sT) where T is the sampling time.
What is the difference between a digital phone and analog cordless phone?
Digital phones are more secure, can send both voice and data transmission, and has better sound quality. Analog phones are less expensive and only transmit voice.
What is need to go with adc converters you are having rectifiers?
<p><p> ADC Converters are those converters which converts continuous quantity to discrete time digital representation.Typically, an ADC is an electronic device that converts an input analog voltage or current to a digital number proportional to the magnitude of the voltage or current. * ADC is converting Analog to Digital,but Rectifiers converts from ALTERNATING CURRENT to DIGITAL CURRENT. ANALOG and ALTERNATING are different concepts. But , Rectifiers are totally different issue, they convert Alternating Current(AC) to Direct Current(DC). They cut the negative waveform from AC wave and make it uni- directional which is called Direct Current(DC) wave.
Difference between an analog and digital scope?
Analog can reach higher speeds.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What is the difference between analog and digital altimeter?
Analog is displayed in a clock like instrument digital is shoun in numbers
Difference between analog audio and digital audio?
In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran
what's the difference between analog and digital watches?
Analog is a clock with the moving hands on it, while digital is computer generated numbers.
Difference between analog digital transduser?
please help me to understand the word transducer
What is difference between vga and lcd display?
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
Difference between analog and hybrid computer?
analog computers,continuous quantities are used. computation are carried out physical quantities such as voltage,length,current,temperature etc. the devices that measure such quantities are analog devices example voltmeter,ammeter.hybrid computer the best qualities of both the digital and analog computer. hybrid computers are best used in hospital. hybrid computers are also used in wheather forecasting.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
What is the difference between analog and digital transmitter?
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
