Decoupling Subsystems � Common-mode currents flowing between subsystems can be effectively blocked with ferrite, common-mode chokes � Another method of decoupling subsystems is insert a filter in the connection wires or lands between the subsystems. This filter can be in the form of R-C packs, ferrite beads, or a combination � High-frequency signals on the power distribution system between subsystems can be reduced by the use of decoupling capacitors
Splitting Crystal/ Oscillator Frequencies � The 16 th harmonics (32MHz and 31.696MHz) are separated by 304kHz, so that they will not add in the bandwidth of the receiver � The 100 th harmonic of the 2MHz signal (200MHz) and the 101 st harmonic of the 1.981MHz signal (200.081MHz) will be within 81kHz of each other and will add in the bandwidth of the receiver
