Abstract
A signal transmission system over building or house wiring includes noise reduction circuit to reduce noise including asynchronous noise and synchronous noise. Received pulses are sampled in a given interval and the number of continous pulses in question during the sampling interval is counted. The pulses in question are ignored as noise if the number of pulse counting is less than a predetermined reference count and the pulses are treated as true signals if the number is more than said reference count.
