An automatic meter reader includes a microprocessor connected through digital logic circuitry and a telephone interface to a metering transducer and a telephone line, to develop modulated signals for reporting of registered meter data and for sampling of received signals to detect a carrier and to effect demodulation and develop control data. A count-down arrangement is used for developing the modulated signals. In sampling received signals, a sample count is developed which is proportional to the duration of one cycle of a received signal and which is compared with stored counts for detection of a carrier and for demodulation. A debounce arrangement is included in the logic circuitry.
