WHERE ELSE ARE RESONANT CIRCUITS USED?
Transmitters also contain many resonant circuits. Most Navy transmitters use a tank circuit to GENERATE an a.c. of radio frequencies. This part of a receiver is the OSCILLATOR. You change the frequency of the oscillator by changing either the capacity of the condensers or the inductance of the coils. In addition to the transmitter’s OSCILLATOR, other tank circuits are used to STRENGTHEN, or AMPLIFY, the oscillator’s feeble a.c. You will hear more about this later in this manual.
