Algorithms
The DSB AM Modulator Passband block transmits the lower and upper sideband signal. For an input signal u(t), as a function of time t, the output is
where:
k represents the Input signal offset parameter.
fc represents the Carrier frequency (Hz) parameter.
θ represents the Initial phase (rad) parameter.
It is common to set the value of k to the maximum absolute value of the negative part of the input signal u(t).
