  • Energy detection circuit for a facsimile system controller
    Patent number: 4567328
    Abstract: Disclosed is an energy detection circuit for use in a facsimile system autodialer/controller. The circuit monitors a telephone line and nulls out transmit tones leaving only receive signals. The analog receive signals are processed to produce a digital signal indicating the on-off times of receive energy on the telephone line. The energy on-off times may then be evaluated by a microprocessor included in the facsimile system autodialer/controller to determine whether a dial tone, busy signal or ring back is being received.
