  • Remote control arrangement using pulse spacing modulator
    Patent number: 4232297
    Abstract: A remote control arrangement uses pulse code modulation for transmission as in infrared remote control arrangements. A feature of the arrangement is that only one quartz oscillator is necessary and is used in the receiver part. The receiver measures the first pulse width transmitted and, dependent on that, defines the measured period of a control circuit. A primary feature is that the arrangement is provided with a prepulse having a threefold pulse width before the start pulse thereby allowing the preamplifier of the receiver to be in its normal operating area when the start pulse occurs.
