WebThe FM waveform is generated by applying the formula given above. The integral of sin (x) is –cos (x) + C. The constant C is not relevant here, so we can use the following equation to compute the FM signal: xF M (t) = sin((10 × 106 × 2πt)− cos(1 × 106 × 2πt)) x F M ( t) = sin ( ( 10 × 10 6 × 2 π t) − cos ( 1 × 10 6 × 2 π t)) http://course.sdu.edu.cn/G2S/eWebEditor/uploadfile/20121213093025493.pdf

Difference between Frequency Modulation and Phase Modulation
