Radio Receivers Indicate the false statement in connection with communications receivers. Double conversion is used to improve image rejection Variable sensitivity is used to eliminate selective fading The noise limiter cuts off the receiver’s output during a noise pulse. A product demodulator could be used for the reception of Morse code.
