Multiplexer Bit Rate Calculation

A multiplexer combines multiple input data streams into a single, higher-speed output stream. To find the total bit rate, we sum the bit rates of all input channels.

Calculating Total Bit Rate

The total bit rate of the multiplexer's output is determined by the number of input channels and the bit rate of each channel.

• Number of input channels: 4
• Bit rate per channel: 100 Kbps

The time slot size (2 bits) is part of the multiplexing scheme but does not directly alter the calculation of the total output bit rate, which is the sum of the input rates.

The formula is:

$ \text{Total Bit Rate} = (\text{Number of Channels}) \times (\text{Bit Rate per Channel}) $

Plugging in the values:

$ \text{Total Bit Rate} = 4 \times 100 \text{ Kbps} $

$ \text{Total Bit Rate} = 400 \text{ Kbps} $

Therefore, the bit rate of the combined output channel is 400 Kbps.
