I am working on a project in which I have to basically output the continuous waveform of the supplied discrete input wave. I am joining the discrete points linearly using an integrator circuit to join the points using a ramp. The following picture will make my project clearer.
**broken link removed**
The problem with this circuit is that the output wave is continuous but all the points of the discrete wave are not properly joined. Also the O/P wave continuously changes its voltage and moves upward. The following picture shows what I mean.
**broken link removed**
See the continuous wave continuously shifts upward.
I am not able to determine what is causing this voltage shift. Does anyone have an idea why this is happening?
P.S : I have tried LM324 and LM358 for making this circuit.
