It is a type of multivibrator circuit that can convert a random amplitude (analog) input signal to output a waveform with uniform amplitude. e.g. Change a sinusoidal waveform to a square waveform.

No it is not!
The schimmit trigger circuit is a logic inverter circuit or a non inverter circuit that has a defined threshold and hysteresis so that the output toggles high at one voltage and toggles low at another voltage.
It is used to create a defined output start from a relatively undefined input state. Commonly used at interface inputs between analogue circuits and digital circuits.

Best regards,
Mark.
