Abstract
A method and circuit to regulate a random waveform signal to ensure that the LED indicator driven by the waveform signal is visible to the human eye is provided. The method and circuit first determines whether there is a pulse occurring. If an on-going pulse is detected, the regulated waveform signal is driven HIGH for at least 8 clock cycles. If no on-going pulse is detected, the regulated waveform signal is driven LOW for at least 8 clock cycles.
