The square wave signal with Levels 
5V produced by the comparator is the
input signal to the integrator. The integrator utilizes
one of the 741 op-amps on the LM324 Quad Op-Amp chip.
The circuit, called an
integrating amplifier or integrator, is shown in Figure 
.
The output voltage of the integrator is the accumulated area of the input voltage
(accumulated as a function of time) multiplied by a constant.
This integral relationship is given by Equation . The integral
relationship between the input and output voltages arises as the result of
the derivative relationship between voltage across and current through a
capacitor.
Given that the square wave signal with Levels 
5V produced by the
comparator is the input signal to the integrator, try to figure out what the
waveform will look like at the output of the integrator.
