Hi,happy new year 2010.

As my attachment below,there are triangular waveform circuit and sine waveform circuit.The frequency and amplitude can be variable.The modulation frequency(Mf)=9,and the modulation amplitude(Ma)=0.8.



so my question is,how to maintain the Modulation Frequency(Mf)=9 since my sine waveform frequency is variable from 1-100Hz?

Modulation index, Ma=Amplitude for sine wave(Am)/Amplitude for triangle(Ac)
Modulation frequency, Mf=Frequency for triangle wave/frequency for sine wave.

Nothing in your circuits seems to be related to modulation. So the question is actually completely unclear.

lock the Mf while changing the fundamental frequency.

as we know there are many benefits of the modulation and one them is long distance transmission. however i don't seems to get the exact idea how it is executed? does E=hf, f-frequency..play the role here? please help
