I wish to be able to have a encoder quadrature signal that I could set the frequency to some specified values (from 10 to 60 Hz). I have a function gen that fulfills the freq requirements but it has only one output.
So the question: is there some kind of circuit (analog or IC) that I could use to add 90 degrees of phase to a signal generated by a function gen, and then use both as they were the outputs of the encoder. It means that the gain should be unitary as well.
If something got misunderstood please ask.
Thanks for any help!!!
