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:

Sample Rate = Twice of Upper Limit = 130,000 x 2 = 260,000 samples/second

Now Back to the Question Statement Calculate the Bit Rate of Upper limit by assuming 6 bits per sample.

Bit Rate = Sampling Rate x No.of bits per sample = 260,000 x 6 = 1560000 bits per second(1.56Mbps)
