Match List I with List II Choose the correct answer from the options given below:LIST I LIST II A. Single polarity positive voltage clipper circuit I. 
B. Negative clamping circuit II. 
C. Differentiator circuit III. 
D. Logarithmic Amplifier IV. 
A-I, B-II, C-IV, D-III
- Identify the type of each circuit from List I and match it with the corresponding image from List II.
- A. Single polarity positive voltage clipper circuit: This circuit is designed to remove or 'clip' the positive half of an input waveform, maintaining only the zero or negative half. Look for a circuit with diodes configured to clip positive voltages.
- B. Negative clamping circuit: This circuit shifts the entire input waveform negatively by a constant DC value. This usually involves a diode, capacitor, and a DC restoration. Look for a circuit configured for DC restoration or clamping.
- C. Differentiator circuit: This circuit outputs the derivative of the input signal, highlighting rapid changes in the signal. Look for a configuration with a capacitor at the input and a resistor in the feedback loop.
- D. Logarithmic Amplifier: This amplifier provides an output proportional to the logarithm of the input. Look for a circuit with diodes or transistors indicating logarithmic conversion.
By matching based on the characteristics and component configurations, we find the correct option to be:
Correct Answer: A-I, B-II, C-IV, D-III
