Question 46
ECNAT2 marksNeeds review
A voice signal
is in the frequency range 5 kHz to 15 kHz. The signal is amplitude-modulated to generate an AM signal
, where
kHz. The AM signal
is to be digitized and archived. This is done by first sampling
at 1.2 times the Nyquist frequency, and then quantizing each sample using a 256-level quantizer. Finally, each quantized sample is binary coded using
bits, where
is the minimum number of bits required for the encoding. The rate, in Megabits per second (rounded off to 2 decimal places), of the resulting stream of coded bits is ______ Mbps.Log in to check the answer
