Are clampers the same as peak detectors? Assess the claim: “Clampers are often called peak detectors.” Choose the most accurate characterization of this statement in the context of diode-capacitor signal conditioning circuits.

Introduction / Context:
Clampers and peak detectors are both diode-capacitor circuits but serve different purposes. Confusing them can lead to incorrect design choices in analog front ends, communication receivers, and instrumentation signal conditioning.

Given Data / Assumptions:

• Ideal diodes and capacitors for conceptual clarity.
• Periodic input signals used for illustration.
• High but finite load resistance unless stated otherwise.

Concept / Approach:
A clamper shifts the entire waveform up or down by adding a DC level so that a selected peak just touches a reference potential. It preserves the shape (apart from small ripple) but re-references the waveform. A peak detector, by contrast, captures and holds the maximum (or minimum) value of the input over time across a storage capacitor, often with a bleed path to track slow changes. Their transfer functions and typical applications differ significantly.

Step-by-Step Solution:

Verification / Alternative check:
Plot outputs: a clamper’s output is a shifted replica of the input; a peak detector’s output is a relatively flat DC level at (or near) the input peak with superimposed decay if loaded.

Why Other Options Are Wrong:

Common Pitfalls:
Assuming any diode-capacitor network is interchangeable; overlooking the role of discharge paths and reference levels.

Final Answer:
Incorrect
