ABSTRACT:
A frequency to voltage transducer for producing an output signal having a value proportional to the magnitude of the frequency of an input signal includes a tunable filter circuit for simulating a resistance - inductance - capacitance (RLC) circuit with a resonant frequency approximately equal to the anticipated base frequency of the input signal. Through appropriate feedback means and multiple gain paths within the simulated RLC circuit, there is provided an output signal which is proportional in magnitude to the frequency of the input signal.
