Such a microphone of the applied voltage. As shown below, the signal is inversely proportional to the total circuit capacitance, so it is essential that the microphone capacitance, the amplifier input capacitance, An equivalent circuit diagram of a condenser microphone is shown in Fig.6.15 Schematic diagram of an electrical circuit that provides a polarizing voltage, Vbias (battery symbol), to the condenser microphone's backplate through an electrical resistor with very large resistance.

That.DC voltage, Vbias, is blocked by a largevalue capacitor acting as a highpass filter to allow only the timevarying voltage, V(t), produced by the changing capacitance of the condenser microphone, to reach the preamplifier, while blocking Vbias from the input to the firststage 1960) A simple method is described for accurately measuring the ratio of the driving current through a capacitortype sound source to the opencircuit voltage of a microphone used as the sound receptor.

A condenser microphone consists a LC resonance circuit with secondary coil of transformer, and 1 MHz oscilation voltage is fed through the transformer to the resonance circuit. Primary and secondary coil coupling of the transformer is very loose, therfore the output voltage of the transformer, resonance voltage, only The Microphone
