Signal dc offset

166

02:03:11

This circuit is used to change the DC offset of a signal without changing it's magnitude or shape. To change the DC offset adjust the potentiometer.

Thanks for your good idea , I re-designed a new version below http://everycircuit.com/circuit/6441665192263680

Nice idea @misaki_david i really like it. I think you can make it even better and simpler like this http://everycircuit.com/circuit/5899031105241088 :)

You could make it a bit simpler like this though http://everycircuit.com/circuit/5875788923273216

@misaki_david yeah i see what your saying but i feel like your adding to much complexity to the circuit for minimal gain.

You can just increase the filter capacitor or resistor value to make it more stable if you need the output to be really precise. (in most cases it probably doesn't matter that much)

In my previous comment I'm taking about this circuit http://everycircuit.com/circuit/5899031105241088

As far as I know. The simple RC network is designed for pure sin wave and not for square wave . Adjustment on RC network will inpact network's frequency range. If we want it perfect, we have to sacrificing something.

Sorry not "inpact" but "impact".

Anyway , they are all good design. Thanks again !

The dc detector is original called "peak detector" http://everycircuit.com/circuit/5027068220538880

Yeah it's interesting to look at different solutions. I guess the best one for a certain situation depends on the application.
