What is the name of the circuit that develops timing signals?

The correct answer is the synchronizer because it is specifically designed to develop timing signals that help ensure proper synchronization within various electronic circuits. Timing signals are crucial in digital systems for coordinating operations such as data transmission, signal processing, and system control.

A synchronizer receives a clock signal and generates a sequence of timing pulses that can be used to drive other components, enabling them to work in unison and avoid timing conflicts. This is especially important in complex systems where multiple signals must be coordinated accurately.

Other options, such as a resolver, primarily serve different functions, such as converting position data into electrical signals, while a pulse forming network is used to shape pulse waveforms rather than create timing signals. Additionally, a video amplifier amplifies video signals for transmission without focusing on developing timing signals. Thus, the role of the synchronizer stands out in its direct involvement with timing signal generation.
