What is a serial-to-parallel converter?

A serial-to-parallel device accepts a series of timed pulses and latches them onto a parallel array of output pins as shown in figure 1. This lab uses a rather simple integrated circuit (IC) known as an 8-bit serial-in/parallel-out shift register (74HC595) as the serial-to-parallel device.

How multiplexer can be used as a parallel to serial converter?

A multiplexer circuit converts parallel data into serial data synchronized with an internal clock signal, and the multiplexer circuit has a logic circuit, a load circuit, and a plurality of switching elements. The logic circuit processes the internal clock signal and the parallel data.

What is the need of parallel to serial converter in PCM?

For serial-form transmission, a parallel-to-serial (P/S) converter converts the parallel-form PCM signal into a serial-form PCM signal. A BNC connector provides the serial-form PCM signal.
