    • A D/A converter is comprised of a string of resistors coupled to a voltage source with respective junctions formed between adjacent resistors, including a reference junction substantially at the mid-point of the resistor string. Plural switches are coupled to the junctions and are selectively operable to couple a potential produced at a respective junction. A subtracting circuit has one input coupled in common to a first set of the switches and another input coupled in common to a second set of the switches to subtract the potential coupled from one set from the potential coupled from the other set so as to produce an output analog signal. A switch control circuit is responsive to a multi-bit digital signal for operating predetermined switches in both the first and second sets and thereby couple to the subtracting circuit the potentials which are produced at corresponding junctions on either side of the reference junction.

    • An FM detector is constructed of a phase shift network and an analog multiplier. The analog multiplier includes a differential amplifier circuit and a phase detector circuit. The differential amplifier circuit includes differential pair transistors which are driven by FM intermediate frequency signals. A base emitter junction of a diode-connected transistor is connected across a base and an emitter of one of the differential pair transistors. The base of the one transistor and a base of the diode-connected transistor are connected to an emitter of an emitter-follower transistor, and the FM intermediate frequency signal is applied to a base of the emitter-follower transistor. Noise which develops in the base of the differential pair transistor or the base of the diode-connected transistor is reduced by the low output impedance of the emitter-follower transistor, so that the signal-to-noise ratio of the FM detector is improved.
