Abstract :
An accurate and stable narrow-band frequency discriminator may be obtained by using two standard dual monolithic crystal filters in parallel, asynchronously tuned. Low deviation from linearity and steep gradient are possible. Theory and experiment are compared for a 10.7 MHz discriminator.
