Chapter 3, Problem 3.22QAP

Interpretation Introduction

Interpretation:

A circuit to perform ${\text{v}}_0=4.0{\displaystyle {\int }_0^t{v}_{1}dt}+8.0{\displaystyle {\int }_0^t{v}_{2}dt}$ should be designed.

Concept introduction:

Operational amplifiers can be used to perform various mathematical operations.

${\text{v}}_0=4.0{\displaystyle {\int }_0^t{v}_{1}dt}+8.0{\displaystyle {\int }_0^t{v}_{2}dt}$

Here shows the addition of the results of two integrations. The diagram shown in following figure illustrates the integration operation using operational amplifier.
