Abstract :
This paper presents an alternative method to generate the digital frequency modulation (FM) signal. By summing an information signal m(k) with the oscillating frequency ω0 and putting the result into the cosine function of digital oscillator coefficient which is −2 cos (ω0 +m(k)), the FM signal is obtained. Computer simulations are conducted to show the validity of the proposed FM signal generator
