The ratio detector is a type of detector circuit, commonly used in radio receivers for demodulating frequency modulated (FM) signal. The ratio detector is a variant of the Foster–Seeley discriminator, but one diode conducts in an opposite direction, and using a tertiary winding in the preceding transformer.
