FM Transmission and Reception
The original frequency modulation (FM) transmitters produced by the General Electric Company were of the direct FM type, utilizing a standard electronic automatic frequency control system similar to that associated with the CBS transmitter. The FM multiplication system in these...
Active Antenna
Antennas that are much shorter than 1/4 wavelength present a very small and highly relative impedance that is dependent on the received frequency. It is difficult to match impedances over a decade of frequency coverage. Instead, input stage Q1 is...
