Frequency Modulation Notes 2 Pdf The ratio of the frequency deviation to the modulating frequency is known as the modulation index (mf). in most communication systems using fm, maximum limits are put on both the frequency deviation and the modulating frequency. Module 2 fm notes free download as word doc (.doc .docx), pdf file (.pdf), text file (.txt) or read online for free. this document covers the fundamentals of frequency modulation (fm) and phase modulation (pm), detailing how a carrier wave can be modulated by varying its frequency or phase.
Eee482 Exp 8 Frequency Modulation Pdf Frequency Modulation Fundamental characteristic of an fm wave is that the frequency deviation ∆f is proportional to the amplitude of the modulating wave, and is independent of the modulation frequency. A frequency discriminator is a device that converts a received fm signal into a voltage that is proportional to the instantaneous frequency of its input without using a local oscillator and, consequently, in a noncoherent manner. In analog modulation the basic parameter such as amplitude, frequency or phase of a sinusoidal carrier is varied in proportion to the baseband signal m(t). this results in amplitude modulation (am) or frequency modulation (fm) or phase modulation (pm). In this unit we will discuss about different modulation and encoding techniques. in this unit both analog and digital modulation will be discussed. further, this unit we will explore how analog signal are converted into digital system and vice versa.

Peak phase deviation represents the maximum phase difference between the transmitted signal and the carrier signal. peak frequency deviation represents the maximum departure of the instantaneous frequency from the carrier frequency. To generate a frequency modulated signal, the frequency of the radio carrier is changed in line with the amplitude of the incoming audio signal. the frequency of the carrier is made to increase as the voltage in the information signal increases and to decrease in frequency as it reduces. When the frequency of the modulator reaches the audible range (> 20hz), we start to perceive other notes, also called sidebands, in the same way with am synthesis.
