Table 7-2.
To calculate the behavior of a transmission system it is important to know the reduction of the
sensitivity due to several influences. The most important are frequency offset due to crystal
oscillator (XTO) and crystal frequency (XTAL) errors, temperature and supply voltage depen-
dency of the noise figure and IF filter bandwidth of the receiver.
