摘要

本文提出了一种产生数字调频(FM)信号的方法。将信息信号m(k)与振荡频率ω0相加，代入数字振荡器系数的余弦函数- 2 cos (ω0 +m(k))，得到调频信号。计算机仿真验证了所提出的调频信号发生器的有效性

Frequency modulation using digital sinusoidal oscillator

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
