Figure shows synchronous TDM with a data stream for each input and one data stream for the output. The unit of data is 1 bit. Find (a) the input bit duration, (b) the output bit rate, (c) the output bit duration and (d) the output frame rate.

Four input streams, each at 1 Mbps, enter the multiplexer; it sends out a single stream of frames, shown in the figure as groups of 4 bits.
