When a frequency-modulated wave is received by more than one path, so that two or more of the voltages which are induced in the antenna have nearly the same amplitude, considerable distortion can result. Large objects, such as hills or high buildings, can reflect and absorb the waves and thus cause interference. Two interfering waves will be in phase part of the time and out of phase part of the time during modulation. This causes amplitude modulation on the resultant carrier, and a sharp… CONTINUE READING
