Voltage swing question

Hi Klaus so are you saying produce a waveform using -3 and +3. Im getting mixed up now.

I don´t know WHERE you are mixed up?
Maybe you mix up INPUT THRESHOLD voltages and OUTPUT SWING VOLTAGES.

The input is a triangle wave so would the output generate a square wave with peaks and troughs of 0V and 3V?

"The maximum output swing of the opamp is ± 3 V with the power supply shown" and the opamp has positive feedback causing its output voltage to have the maximum output swing.

The next question asked by your teacher will probably be, "at what input threshold voltages does the comparator output change directions?" and I show them here:
EDIT: I corrected the voltage on my sketch.

Hi,

Sorry i'm a little confused here do I sketch a graph with triangle waves or square waves from -3 to +3?

The triangle wave input is a that goes from -4.5V to +4.5V.
Since the opamp has positive feedback then its squarewave output goes to its maximums of -3V and +3V.
 

OK, here is the expected output wavefrom, in red, superimposed to the graph of the input voltage:



I hope now is clear
