Transcription: Let's first look at clipping circuits. It is required in some cases to clip the positive or negative peaks, or both, of the input signal. An example is in radio communication where undesired peaks are created by the presence of noise. These peaks are required to be eliminated for proper signal reception. The circuit used to clip the positive peaks of a signal is shown. This type of circuit is called a diode clipping circuit. of circuit is also known as a positive limiting circuit. When the voltage at point A is greater than the battery voltage V sub B by 0.7 volts, assuming a silicon diode, th ...
