Question

An analog signal is sampled at 36 khz and quantized into 256 levels. the time duration of a bit of the binary coded signal is

Answer 1

Answer: the sampling frequency is 36khz

And the original signal frequency is 18khz

So don't confused as fm value is given.

The time duration of sampling frequency signal is 2.7*10^-5

So now divide the Ts by 8.

Because we need Ts of one bit.

It is 3.47micro seconds.
