Answer:
The circuit that generates a spike in response to a momentary change of input signal is called an R-C differentiator circuit. Let's understand why this is the correct answer in detail.
1. Differentiator Circuit:
A differentiator circuit is a type of electronic circuit that produces an output voltage proportional to the rate of change of the input voltage. It amplifies high-frequency components and attenuates low-frequency components of the input signal. The differentiator circuit is widely used in various applications such as signal processing, communication systems, and control systems.
2. R-C Differentiator Circuit:
The R-C differentiator circuit consists of a resistor (R) and a capacitor (C) connected in series. The input signal is connected across the resistor, and the output voltage is taken across the capacitor. When a sudden change occurs in the input voltage, the differentiator circuit produces a spike or pulse at the output.
3. Working Principle:
When the input voltage changes suddenly, a high rate of change in voltage occurs across the resistor. This causes a large current to flow through the resistor, which charges or discharges the capacitor rapidly. The capacitor acts as a differentiator element, allowing high-frequency components to pass through and attenuating low-frequency components.
4. Output Spike Generation:
Since the capacitor charges or discharges rapidly in response to a sudden change in input voltage, a spike or pulse is generated at the output. This spike represents the rate of change of the input signal. The amplitude and duration of the spike depend on the magnitude and duration of the input voltage change.
5. Applications:
The R-C differentiator circuit is commonly used in applications where the detection or measurement of rapid changes in input signals is required. It is used in pulse detection circuits, frequency modulation (FM) systems, edge detection circuits, and signal processing applications.
In conclusion, the circuit that generates a spike in response to a momentary change of input signal is called an R-C differentiator circuit. It is a widely used circuit in various applications where the detection of rapid changes in input signals is necessary.
