F05 - Basics of Transmitters

Which of these is true of a basic transmitter
1. The signal from the microphone connects to the modulator
2. The oscillator feeds into the audio amplifier
3. The audio stage feeds into the oscillator
4. The oscillator feeds into the modulator
In a basic transmitter the antenna connects to the
1. RF power amplifier stage
2. The audio amplifier stage
3. The oscillator stage
4. The modulator stage
In a basic transmitter the output frequency is determined by the:
