A signal m(t) band-limited to 10KHz is sampled at a rate 50% higher than nyquist rate. Find Nyquist rate and sampling rate. What is the sampling range with signal distortion? No. 5 For 7-Bit decoding: Assume Compression Parameter to be 100, pls estimate the signal to noise ratio.

Solution

4) nyquist rate = 2* bandwidth

= 20 KHz

sampling rate = nyquist rate * 1.5

= 30 KHz

5) signal to noise ratio = 2²ⁿ

ⁿ⁼⁷

= 16 K
