h34r: i need to write a three page report on the integrator. every textbook i look at says the integrator performs the operation of integration.
ok, thats fine, but i need an example!!!

for an example u can take the integrator convets a square wave into an triangular waveform
a sine wave into a -ve cosine wave. and so on
ie the output voltage is the area other the input voltage curve

hey ......even I have heard that integrator converts square waveform to triangular.........but I am not getting it........what may be the problem?

the capacitor in the circuit is responsible for that.
thanks haditya for the area under the curve bit. i didnt know that.

hey girl,u can basically make ur report in three parts as follows:
1.draw the diagram and tell what each component does.
2.derive the equation for integrator.
3 applications of integrator.one of the examples can be that we use integrator in FUNCTION GENERATOR to convert triangular wave of function generator into square wave.the reason for getting a triangular waveform from integrator is charging and discharging of feedback capacitor.

hope this was of some help to you.

hi gauri

check on my reply #3197. its about interation and triangle wave generation you can use the chip TL072.

hi,

here's an update on the triangle wave oscillator. still using using the same circuit and adding 3 components you can now change that circuit into a sawtooth wave oscillator.

i need 2 write a lab report bout differentiator amplifier!
but through all my search, no details i have except differential amplifier!
