Block diagram of an FM quadrature detector. Modulation index and deviation ratio ... In other words, for a VHF FM broadcast station with a deviation of ±75 kHz and a maximum modulation frequency of 15 ...

The figure below shows a block diagram of a table-top AM radio from the late 40’s where the radio tunes in stations at the frequency frf = frequency of OSC1 – 455 kHz.

In this application the modulation scheme targets Altera’s Cyclone-IV FPGA populated on a DE2-115 development board from Terasic and an HSMC (High Speed Mezzanine Card). A system block diagram shows ...
