hi everyone.
I need to encrypt speech that is being transmitted over FM (20kHz)
I can encrypt speech signal while its analog (is there any IC i can use ?)
or convert it to digital and then encrypt it.
the method using for encryption should be simple.
any idea where should I start ? any reliable source ?
which one do you think would be easier digital or analog ?
I googled it and know the basics, but I don't know where to start.
thanks everyone.
