Abstract
A receiver circuit relies on sample data techniques to filter input data signals having a frequency less than a preselected maximum and greater than a preselected minimum. The circuit also rejects a single sine wave cycle. If an input pulse greater than a preselected maximum termination pulse width is encountered during data reception, then reception activity is terminated.
