Abstract
A circuit provides electrical isolation from an input signal which has a leading edge and a trailing edge. On the leading edge of the input signal, a first signal is transmitted across an isolation device to provide a first isolated signal representative of the leading edge of the input signal. On the trailing edge of the input signal, a second signal is transmitted across the isolation device to provide a second isolated signal representative of the trailing edge of the input signal. The first and second isolated signals are electrically isolated from and representative of the input signal.
