Abstract :
Clock modulation has the role of reducing electromagnetic interference (EMI) by spreading the spectrum of the clock signal. This method is implemented in the Fujitsu 16 bit and 32 bit microcontrollers. Experiments were conducted on the MB91F362GA microcontroller, with the modulated clock extracted on a special pin and the emitted signals measured with a spectrum analyzer.
