Question 2: (5 Marks)
In Dolphins, the audible range of frequencies is usually 1000 to 130,000 Hz. You have to calculate the bit rate of upper limit assuming 6 bits per sample.
Solution:
No of bits per sample=6 bits/sample
Highest feq=130,000 HZ
According to nyquist theorem
Sampling rate=2(highest freq) samples/sec
Sampling rate=2(130,000)=260,000 samples/sec
Bit rate=sampling rate X No.of bits/sample
Bit rate=260,000 X 6 bits/sec
=156,000,0 bits/se
