Assertion (A): A high value of resistor is connected across the diode in a clamper circuit for better performance.
Reason (R): If this resistor is not present, the circuit will respond to sudden decrease in the magnitude of the input pulse train, but the response to sudden increase in the amplitude will cause improper response.
Explanation:
Clamper circuits are used to shift the DC level of a waveform. They are commonly used in applications such as video signal processing, where it is necessary to shift the DC level of the video signal to a desired level.
Working of a Clamper Circuit:
A clamper circuit consists of a diode, a capacitor, and a resistor. The diode is typically connected in series with the capacitor and the resistor is connected across the diode. The input waveform is applied across the series combination of the diode and the capacitor.
When the input waveform is positive, the diode is forward-biased and charges the capacitor to the peak value of the positive input waveform. The voltage across the capacitor is then added to the input waveform, shifting the DC level of the waveform. When the input waveform is negative, the diode is reverse-biased and the capacitor retains its charge, resulting in the shifting of the DC level.
Role of the Resistor:
The resistor connected across the diode in a clamper circuit serves multiple purposes:
1. Discharge Path: The resistor provides a discharge path for the capacitor when the input waveform is negative. This ensures that the capacitor is discharged properly before the next positive cycle of the input waveform.
2. Protective Role: The resistor limits the current flowing through the diode, preventing it from getting damaged due to excessive current. It acts as a protective element.
3. Proper Response: The high value of the resistor ensures that the circuit responds properly to sudden increases in the amplitude of the input pulse train. If the resistor is not present or has a low value, the sudden increase in amplitude may cause improper response or distortion in the output waveform.
Therefore, both the assertion (A) and the reason (R) are true, and the reason (R) provides the correct explanation for the assertion (A). The presence of a high-value resistor across the diode in a clamper circuit is essential for better performance and proper response to input waveforms.
Reason (R): If this resistor is not present, the circuit will respond to sudden decrease in the magnitude of the input pulse train, but the response to sudden increase in the amplitude will cause improper response.
