Frequency, voltage, voltage offset, current, phase shift?
A schmitt trigger may be useful to generate square wave, but you have to take care about input voltage levels and voltage offset.
As it includes a hysteresis .. it will generate a phase shifted square wave (if adjusted for symmetric output).
Depending on shift angle one solution could be to first shift the sine, then use a schmitt trigger.
(Using an RC after the schmitt trigger will destroy square wave)
Now you have two frequencies. it´s not a simple sinewave anymore. How comes?
A filtered sine wave will remain a sinewave. Frequency will still be the same, just amplidute and phase may change. I wonder why there is a second frequency.
..and how you want to generate a square wave from two interlaced sinewaves..
Maybe do a simulation. There are free simulation tools. Even Excel can do this job.
