Other Parts Discussed in Thread: VCA810
Dear all,
my need is to generate an harmonic signal (sine wave) with a frequency tuned between 0 and 1 kHz and the amplitude controlled between 0 and 1 Vrms. As analogic inputs to control frequency and amplitude, I can provide current and/or voltage (dc) signals.
I am guessing to use the LM331 to control the frequency and feed the generated signal to a VCA810 (or equivalent) to control the amplitude.
What is the amplitude of the signal generated by the LM331? Does it depend somehow on the analogic input signal as the frequency (formula to calculate?) or is it constant?
Could you please confirm that this solution make sense?
Thank you
Leonardo
