Compensated Attenuator
A compensated attenuator is a type of circuit that is designed to attenuate or reduce the amplitude of a signal while keeping the transfer function independent of the frequency. In other words, the output of the circuit will have the same magnitude regardless of the frequency of the input signal.
Transfer Function
The transfer function of a circuit describes the relationship between the input and output signals in the frequency domain. It is usually represented as a ratio of the output signal to the input signal. In the case of a compensated attenuator, the transfer function remains constant regardless of the frequency.
Answer Explanation
The correct answer is option 'C', which states that the transfer function of a compensated attenuator is independent of the frequency.
When a circuit is called a compensated attenuator, it means that it is designed to provide a constant attenuation or reduction in the amplitude of the input signal. This is achieved by using components and circuit configurations that ensure a consistent output regardless of the frequency of the input signal.
In other words, a compensated attenuator is designed to compensate for any changes in the transfer function that would normally occur with variations in frequency. This is important in applications where the magnitude of the signal needs to be accurately controlled, such as in audio systems or instrumentation.
By keeping the transfer function independent of the frequency, a compensated attenuator ensures that the output signal faithfully represents the input signal, but with a reduced amplitude. This is achieved by carefully selecting the values of the components and using circuit techniques that minimize frequency-dependent effects.
In contrast, options 'A', 'B', and 'D' describe scenarios where the transfer function of the circuit would vary with the frequency. In option 'A', the transfer function would directly vary with the frequency. In option 'B', the transfer function would vary inversely with the frequency. In option 'D', the natural log of the transfer function would be proportional to the frequency.
Therefore, the correct answer is option 'C', where the transfer function remains constant regardless of the frequency, indicating a compensated attenuator.
