Frequency Modulation Recording

Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used to frequency modulate a carrier, i.e. the carrier signal is frequency modulated by the input signal (FM modula¬≠tion), which is then recorded on the tape […]
