A1. Direct record (AM).
    Frequency modulation (FM).
A2. It takes the signal from the summing network, amplifies it, and sends it to the record head for recording.
A3. It generates an equalization signal which corrects any Frequency response problems in the input signal from the pre-amplifier circuit.
A4. Instead of recording the signal just as it appears at the recorder's input, FM record electronics records a frequency-modulated carrier signal from a record oscillator (figure 5-4)onto the magnetic tape.
A5. It amplifies the frequency-modulated output from the record oscillator and sends it to the record head.
A6. FM record electronics must use a limiter and demodulator circuit (figure 5-5) to demodulate the signal intelligence from the carrier frequency.
