Abstract : The patent describes a system for measuring the phase difference between two signals and having a digital readout. Each of the two signals are fed to Schmitt trigger circuits which convert the sine wave signals to square waves. The two square waves are compared for coincidence in a discriminator, the output thereof being converted by a logic circuit to a form for displaying the digital phase difference of the two signals.
