Explanation

The computer that processes both analog and digital signal is called hybrid computer.

Hybrid computers are computers that exhibit features of analog computers and digital computers.

The digital component normally serves as the controller and provides logical and numerical operations,

while the analog component often serves as a solver of differential equations and other mathematically complex problems.

Explanation

Hertz (Hz) is the unit used to measure the frequency of an analog signal, and higher frequency means higher bandwidth.

Bandwidth in analog signals refers to the range of frequencies, which is expressed in Hertz.

Explanation

For point to point analog signaling, a bandwidth of up to about  1 MHz is possible.

Analog bandwidth is the maximum sinusoidal frequency of the analog signal the circuit works with. 

Explanation

Good voice reproduction via PCM can be achieved with 128 quantization levels, or 7-bit coding (27 = 128). A voice signal, conservatively, occupies a bandwidth of 4 kHz. 

Explanation

A baseband signal can be transmitted over a pair of wires (like in a telephone), coaxial cables, or optical fibers

Explanation

Input is never converted to digital form.

Explanation

The most common technique to change an analog signal to digital data is called pulse code modulation (PCM). A technique used by codes to convert an analog signal into a digital bit stream is known as Pulse code modulation.
