Frequency modulation (fm) is a type of modulation where the frequency of the carrier is varied in accordance with the modulating signal. the amplitude of the carrier remains constant.

Operational Amplifier Opamp Simulation Electrical Engineering Stack The higher frequency signal is the carrier frequency, while the original signal is the data that you want to relay. we will use the data signal to modulate a much higher frequency carrier wave. Frequency modulation (simulation experiment). retrieved 2 april 2026, from vlab.amrita.edu index ?sub=59&brch=163&sim=261&cnt=475. The fm modulation is achieved by modulating the hysteresis, which influences the oscillator frequency. an audio signal of about 20 mvpp is sufficient for a reasonable output amplitude. In this article, we provided solved examples of fm modulator design for both the reactance modulator and armstrong's indirect method. i hope these examples, together with the concepts presented in the previous articles, help you better appreciate the complexities in fm signal generation.

Firstly, unlike normal oscillators that contain transistors this one does not have any inductors. secondly, there is no need for a varicap diode to do the fm modulation. the opamp is configured as a schmitt trigger with only a small amount of hysteresis. the output is fed back via an rc circuit. The fm modulation is achieved by modulating the hysteresis, which influences the oscillator frequency. an audio signal of about 20 mvpp is sufficient for a reasonable output amplitude. It is also possible to perform these lab activities using the adalm1000 (m1k) hardware module with minor adjustments to the circuits. this document outlines how the labs might be altered for use with m1k and the alice desktop software. The following demonstration will introduce more practical aspects of frequency modulation and examine the effect of the carrier frequency and fm deviation on the resulting fm signal.
