ABSTRACT:
A digital phase frequency discriminator is disclosed that eliminates crossover distortion problem inherent in previous discriminator without a corresponding increase in complexity in the circuit. The discriminator includes four cross-coupled RS latches and a reset gate. The reset gate is coupled to the latches such that additional gate delays are provided to ensure that the output signals of the discriminator reach these full logic amplitude and thereby allow for accurate phase frequency discrimination to occur.
