  • Abstract
    A remote control system for tv receivers is described which employs ultrasound in the vicinity of 40 kc. Slowly decaying single-frequency signals are produced by striking aluminum rods with a hammer. The receiver employs limiting followed by frequency selection and integration to discriminate against acoustic interference.
