Matlab scripts for signal processing.

ana_c_ana_m.m: Plots carrier, modulator, AM, PM and FM signals in time and frequency domains.
n_ask.m: Plots an N-level encoded modulator and the corresponding ASK in time and frequency domains.
n_fsk.m: Plots an N-level encoded modulator and the corresponding FSK in time and freq. domains.
sampling_test.m: Compares how signal length affects the result of the FFT accuracy.
mag_pahse_test.m: Compares different methods to calculate and plot the magnitude and phase of a given signal.
n_psk.m: Generates a PSK modulation and plots the modulator and the modulated signal in time as well as in the frequency domain.
vector_gen_test.m: This file is a Matlab script that compares 2 different ways to generate a vector.
IQmod_demod.m: This file is a Matlab script that generates IQ modulation and demodulates back to the orginal signal.
pam.m: This file is a Matlab script that generates a PAM modulation.
pwm.m: PWM (Pulse width modulation) signal generation Matlab script.
delta_pwm.m: Delta PWM modulation.
delta_sigma_pwm.m: Delta-Sigma PWM modulation. pfm.m: Pulse Frequency Modulation (Integral Pulse Frequency Modulator).
