Why it is generly true that a digital signal required high bandwidth than analog signal?
A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.
Every pulse in a digital signal?
Bit
What is the bit rate of the Pam signal?
32 kHz
What is the quantization interval of a 10 bit converter covering the range from 5 to -5 volts?
No. of quantization levels = 2^10 = 1024Voltage range = 10VQuantization interval = 10/1024 = 9.77 mV / level.
What is different between digital and analog?
Consider this:You want so signal your friend using a torch light. Now you might think there is only one way to signal to your friend by turning on and off the flashlight right? But actually there are more ways.1) Turning on and off the flashlight2) Dimming the torchlight and bringing it back to full shineSo here method 1) is the digital way to signal to your friend and method 2) is the analog way to signal to your friend.Difference: In method one its either full signal or null as in case of digital signal 0 or 1In method two there is always signal(torch is always glowing) but we are signaling by dimming the glow of light.cheers,...kamIn electronics, the term "digital" refers to circuits in which individual data are represented by a discrete set of voltages -- usually only two (i.e., either a "logic 1" or a "logic 0"). In this case, each datum is a binary entity called a bit. Data in the form of numbers other than 0 or 1 (e.g., 2, 365, 3.14159, etc.) are represented as patterns of bits.In analog circuits, each datum is encoded as a continuous voltage within a range. Such circuits are widely used in such application areas as audio electronics, radio, motor control, etc.Historically (c. 1960), analog computers were developed that competed with digital computers. However, digital circuits are at the heart of virtually all modern computers.
