Binary Frequency -Shift Keying (BFSK) • Two binary digits represented by two different frequencies near the carrier frequency – where f 1 and f 2 are offset from carrier frequency f c by equal but opposite amounts – B = 2([f 2 – f 1]/2 + f b) • Where f

In both cases above, if the modulating signal is a digital waveform, then the resulting FM signal is a frequency-shift-keying signal (FSK) which you have seen in experiment #2. 3.0 FM Detection (FM Discriminators): FM detection is the secret for the success of FM broadcasts. Basically, one can design an FM detector, called a
