Abstract
A CMOS device for generating a waveformn envelope is provided in a network that uses a twisted pair medium, such as a telephone line, to connect stations. The CMOS device receives analog signals representing pulsed data signals sent over the telephone line and generates an envelope waveform for the received analog signal. The envelope waveform can then be used to detect the arrival of data, as opposed to noise on the network.
