A TDM link has 24 signals and each channel is sampled 8000 times/sec. Each sample is represented by 8 binary bits and it contains an additional bit for synchronization. The total bit rate made from the TDM link is 

Concept:

Time Division Multiplexing (TDM) provides the time-sharing of a common channel by a large number of users.

The data sources are sampled at a Nyquist rate or higher.

Proper operation depends on synchronization between the input and the output communications.

Calculation:

Given sampling rate of channel each = 8000 Hz = f_ch

Since 24 such signals are Multiplexed, we get a total pulse per second (frequency) of the multiplied signal as:

f_s = nf_ch

Putting on the respective values:

f_s = 24 × 8000

f_s = 192,000 = 192 KHz

Now each sample is represented by 8 bits and contains an additional bit for synchronization (n).

The total no. of bits per sample will be:

n = 8 + 1 = 9 bits

∴ The total bit rate of TDM link is given as:

R_b = nf_s

R_b = 9 × 192 Kbps
