Method and Circuit Arrangement for Converting a Sine Wave Signal into a Square Wave Signal

A method for converting a sine wave signal into a square wave signal includes inputting the sine wave signal at an input of a threshold-value device that generates the square wave signal. The square wave signal is generated by comparing a sine wave signal value to a predefined threshold value, and the square wave signal is output at an output of the threshold-value device. An actuating signal is superposed on the sine wave signal at the input of the threshold-value device. The actuating signal is generated by forming an average-value signal representing an average value of the square wave signal and inputting the average-value signal at an input of a control amplifier device for generating, as the actuating signal, a signal representing a difference between an average-value signal actual value and a predefined average-value signal nominal value.
