ABSTRACT:
Apparatus for determining whether the ratio of the widths of a pair of signals is within acceptable limits including integrator means, including a first integrator responsive to a first signal to integrate in a first direction at a first rate and to a second signal to integrate in the opposite direction at a second rate and a second integrator responsive to the first signal to integrate in the first direction at the second rate and to a second signal to integrate in the opposite direction at the first rate; indicator means responsive to the integrator means for providing a data signal representative of the first and second signals have the proper ratio beginning in response to the second integrator reaching a first predetermined level and ending in response to the first integrator reaching a second predetermined level and control means, responsive to the end of the second signal occurring during the presence of the data signal to provide a clock signal validating the data signal and to the end of the second signal occurring separately of the data signal to reject that data signal.
