Capacity of Binary Channel:

  • Binary channel has a capacity of 36 kbps.



Bandwidth of Signal:

  • Signal is bandwidth limited to 3.2 kHz.



Quantizing Level:

  • Quantizing level refers to the number of discrete levels that a signal can be divided into during quantization.

  • The appropriate value of quantizing level can be calculated using the formula:

  • Quantizing Level = 2^(Number of bits per sample)



Sampling Frequency:

  • Sampling frequency refers to the number of samples taken per second.

  • The appropriate value of sampling frequency can be calculated using the formula:

  • Sampling Frequency = Bandwidth of Signal * Quantizing Level



Calculations:

  • Since the capacity of binary channel is 36 kbps, the maximum bit rate that can be used for voice transmission is 36 kbps.

  • For voice transmission, the signal is bandwidted to 3.2 kHz.

  • The maximum number of bits that can be used per sample is given by:

  • Number of bits per sample = log2(Quantizing Level)

  • Using the formula for sampling frequency:

  • Sampling Frequency = Bandwidth of Signal * Quantizing Level

  • Substituting the values:

  • 36 kbps = 3200 Hz * Quantizing Level * log2(Quantizing Level)

  • Solving the above equation, we get Quantizing Level = 64

  • Substituting the value of Quantizing Level and Bandwidth of Signal in the formula for Sampling Frequency, we get:

  • Sampling Frequency = 3200 Hz * 64 = 204.8 kHz



Answer:

  • The appropriate values of quantizing level and the sampling frequency for the given binary channel and bandwidth of signal are 64 and 204.8 kHz, respectively.

  • The correct option is B. 64 and 7.2 kHz.
