A technique used by codes to convert an analog signal into a digital bit stream is known as __________.
The correct option is A Pulse code modulation
A technique used by codes to convert an analog signal
into a digital bit stream is known as Pulse code modulation.
Pulse-code modulation (PCM) is a method used to digitally
represent sampled analog signals. It is the standard form of digital audio in
computers, compact discs, digital telephony and other digital audio
applications. In a PCM stream, the amplitude of the analog signal is sampled
regularly at uniform intervals, and each sample is quantized to the nearest
value within a range of digital steps.
Modulation is the process of varying one or more
parameters of a carrier signal in accordance with the instantaneous values of
the message signal.The message signal is the signal which is being transmitted
for communication and the carrier signal is a high frequency signal which has
no data, but is used for long distance transmission.
There are many modulation techniques, which are
classified according to the type of modulation employed. Of them all, the
digital modulation technique used is Pulse Code Modulation (PCM).
