I'd like to know whether SigmaDSP can support the tone source with changeable frequency.
For example, s=sin(2*pi*f(t)*n*Ts), here the frequency f(t) is changeable and is yielded from some other program calculation result.
SigmaStudio includes a few different tone sources in the Sources library. A simple sine tone generator that is controlled with a parameter word is under the Oscillators category. If you want to control the frequency of the tone with another signal in the SigmaDSP, then you should look at the voltage-controlled oscillator (VCO). The VCO block has an input pin that can be used to modulate the frequency of the output tone.
