Hi all,
For my next project, I need to mix 2 sinusoidal frequencies.
I've found some modulator IC (Ex. MC1496) and some modules on Aliexpress, but the problem with those is that they work with high frequencies (Ex: 85 to 108 kHz).
The frequencies I need to mix are a lot lower AND they have (more or less) the same order of magnitude.
An example of frequencies I want to mix is:
- carrier frequency : 311 Hz.
- modulating frequency : 7 Hz.
The amplitudes of those frequencies are not equal (one of the signals is stronger than the other) thus I need to equalize the amplitudes, before mixing them.
Can somebody point me to the right direction?
Ideally, I would like to find a module already made, but if there is none, I know how to conceive a PCB an solder the components on it.
Thank you all for the time you consumed in reading this message.
