8. 836700 Operation RE BROADCASTING LIMITATIONS Signal Strength The signal strength is a major factor when a signal is re broadcasted measured and evaluated FM compared to AM is less susceptible to the inherent noise of the radio reception When speaking about FM broadcasting it is the monaural reception which can tolerate and profit from a much narrower IF bandwidth The stereo reception adds all noise present in the 23 53 kHz sub band The amplitude component AM of the sub band is converted down to audible noise and added to the program signal That is why the noise performance of FM stereo can be as much as 20 dB worse than that of monaural broadcast Better reception and measurement can be obtained by using highly directional outdoors antenna This will improve the signal strength and contribute in eliminating the multipath distortion Multipath Distortion In FM reception regardless of overall signal strength a very important consideration is that obstacles which an FM signal may encounter in the line of sight path tend to reflect and disperse the signal in many directions In many locations especially in urban areas where many tall buildings interfere with the direct transmitted signal or in suburban areas surrounded by hills or mountains an FM receiver may pick up a station s primary signal but also several secondary reflections coming from various directions These reflections arrive at the receiver out of phase slightly d
