Abstract
In a Foster-Seeley discriminator circuit having a discriminating resonance circuit, resonance circuits having series resonance characteristics are respectively connected between a signal source and both ends of the discriminating resonance circuit so as to raise the level of a composite output voltage of the frequency discriminator circuit, whereby the sensitivity of the output voltage versus the frequency can be enhanced.
