✔our main focus is on angular modulation and demodulation. We will take into account both frequency modulation (FM) and phase modulation (PM), and observe their behaviors in time and frequency domains. FM and PM are, respectively, defined as FM: Acos (wet + kf from(t)), PM: Acos(wet+kpm(t)). π 6' The FM and PM coefficients, (kf and kp) are kf = 60 and kp = 1, respectively. The carrier frequency is 600 Hz. (1) Plot both the time-domain and frequency-domain representation for two independent message signals, m₁(t) and m²(t) using MATLAB.
