Diference between Open and closed clippers

Open and closed clippers refer to two different types of tools commonly used in various applications, especially in the context of electronics, signal processing, and control systems. Let’s delve into the differences between open vs closed clippers:

Open Clippers: Open clippers, also known as diode clippers or unilateral clippers, are electronic circuits that modify the shape of an input waveform by allowing only a certain portion of the waveform to pass through while clipping or limiting the rest. In an open clipper circuit, a diode is usually used to “clip” the signal. When the input voltage exceeds a certain threshold, the diode becomes forward-biased, and the excess voltage is dropped across the diode, limiting the output voltage.

Closed Clippers: Closed clippers, also referred to as bilateral clippers, involve a more complex circuit that employs two diodes in opposite directions. These clippers are capable of both positive and negative clipping, which means they can limit both the positive and negative excursions of the input waveform.

In summary:

Open Clippers: These clippers are simpler and allow clipping in only one direction (either positive or negative, but not both). They are commonly used for simple limiting or signal protection applications.

Closed Clippers: These clippers are more versatile and can clip both positive and negative portions of the input waveform.. They are usedwhen the waveform needs tobe modifiedin both directions.

In various applications, the choice between open and closed clippers depends on the specific requirements of the circuit and the desired waveform modification. Open clippers are suitable for basic clipping needs, while closed clippers offer greater flexibility and control over waveform shaping.
