A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.
No, PCM is simply a digital representation of an analog signal. The actual analog to digital conversion is done by an analog-to-digital converter.
Analog TV:Analog (or analogue) television encodes television picture and sound information and transmits it as an analog signal: one in which the message conveyed by the broadcast signal is a function of deliberate variations in the amplitude and/or frequency of the signal. All systems preceding digital television, such as NTSC, PAL or SECAM are analog television systems. Digital TV:Digital television (DTV) is the sending and receiving of moving images and sound by discrete (digital) signals, in contrast to the analog signals used by analog TV.
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.

Quantizing
Its an IC which converts the analog signal at its input into digital output suitable for digital applications. It is an essential part of any digital system
It is a digital to analog converter or D to A converter. The reverse device is an analog to digital converter or A to D.
This is a 2 step process:a microphone converts the sound to an analog electrical signalan analog to digital converter converts the analog electrical signal to a digital stream of binary coded values
modelm
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.
