FM Frequency Modulation Index & Deviation Ratio ...

The frequency modulation index is the equivalent of the modulation index for AM , but obviously related to FM. In view of the differences between the two forms of modulation, the FM modulation index is measured in a different way. The FM modulation index is equal to the ratio of the frequency deviation to the modulating …

The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. FM radio maybe appropriately referred to as "high-fidelity." If FM transmitters use a maximum modulation index of about 5.0, so the resulting bandwidth is 180 kHz (roughly 0.2 MHz).

TV AUDIO DEVIATION MEASURING AND SETTING IT By Frank F. Mcclatchie FM SYSTEMS, INC. 800-235-6960 Measurement and control of TV audio volume has always been with us, but other concerns have usually taken precedence. Loudness contrast between channels is accentuated by program source switching and local ad insertion, not

will discuss deviation a bit later. 4. An FM transmitter has constant RF power output regardless of its audio input. Depending on the audio input to the modulator, the energy from an FM transmitter is distributed across the transmitted bandwidth in various ways. a. An un-modulated transmission, of course, has all the power at the carrier
