Characteristic Equation

Voltage Integrator Parameters and Defaults

1.33.1 Investigations

1. In the initial circuit, the input signal is symmetrical (+/- 5V) about the zero axis and the

integrator output is zero for sine, square and triangle waveforms.

2. To make the waveforms unsymmetrical about the zero axis use the OFFSET control on the

function generator. Setting the OFFSET equal to the AMPLITUDE setting will reference

the input to ground (0V).

In this case, the output is always positive. When output is high, “area” is continually added.

Output will rise indefinitely.
