Abstract
Disclosed is a pulsed FM receiver with automatic centering of the intermediate frequency at the true center of the input filter passband. The frequency standard of the frequency discriminator which controls the local oscillator frequency is adjusted to produce zero discriminator output during the period between signal pulses. The discriminator frequency standard remains automatically aligned with the center of the input filter passband and the input bandwidth may then be reduced for optimum receiver sensitivity.
