AM AND FM RECEPTION
The following is a brief explanation of AM an<
reception characteristics.
Signal Transmission—The range of normal he:
is approximately 30 Hz (cyles per second) to 14,00(
AM has a range of 50 to 5000 Hz. On the other hand
covers the entire range of normal hearing. Both AM
FM are received on a regular radio as a monaural sig
FM/Stereo receivers are capable of receiving
monaural and FM stereophonic broadcasts. These st
broadcasts are sometimes referred to as multiplex.
Fading—Fading is not usually a problem with
because of its long distance reception capability
3V-10). FM, on the other hand, is limited under avei
conditions by terrain and transmitted power (fig.
11). The area of good FM/Stereo reception may eve:
slightly less than that of regular FM because of stror
signal requirements. Figure 3V-12 illustrates fading
an FM signal due to differences in terrain. Recep;
behind hills may be noisy (hissing or popping). 1
noisy reception is sometimes referred to as flutter
"picket fencing."
