Often used with switching transistors and high-power electronics to filter out noise in power supply lines, ferrite beads employ magnetic materials to produce a lossy inductance when inserted into a circuit. While ferrite beads themselves can be relatively simple in their design (e...
(RC RL or ferrite beads) are added in hopes that this may fix the problem Also the crystal frequency may be reduced by about 2x to run the system clock at a slower rate Software may have to be rewritten to compensate for this new time base Software can be redone to toggle the outputs...
