An analog signal is to be coded by an ADC. The signal contains significant frequencies up to 3.2kHz. If the
system is operated at a bit rate of 36,000 bits per second (bps), answer the following:
a) To avoid aliasing, the sampling frequency must be greater than or equal to
kHz
b) If the signal is sampled at the Nyquist rate, what is the Nyquist frequency?
kHz

c) If the signal is sampled at the Nyquist rate, the number of bits per sample is
number of quantization levels is
and the
Note:
*When you use the formula bFs < Bit Rate in finding b, the result must be rounded down to the nearest
integer.
**When you use the formula 2 > L in finding b, the result must be rounded up to the nearest integer.
