Analog computation using OPAMP ll electronics ll msc final

analog computation: this is the third application of OPAMP analog computation means to compute the given equation the given equation may be a differential equation or pressure or temperature or length or height etc. in this video we will learn how to compute a given differential equation of second order using OPAMP as an integrator and as an inverting summing amplifier we can also use differentiator instead of integrator but it has some limitations : 1) noise in differentiator increase with increases in frequency of signal 2) it is highly sensitive to noise so it can easily sense the noise and then it will amplify it 3) it is not convenient to introduce initial conditions at the input of differentiator
