    They are the same ground, if you use an adapter for your DC power that is.

    The ground from DC can also be the negative pole only if you just use the '+' and '-' of the battery...

    In amplifiers ac ground means signal ground & dc ground means powersupply ground.

    Re: difference between ac ground and dc ground

    if u study about the opamp and its design , u can find the differenc between them.

    follow the following book

    design of analog cmos integrated circuits by behzad razavi.

    difference between ac ground and dc ground

    Although there can be times in power circuits where AC ground is separate from DC ground, you are probably confusing the terms with AC-grounded and DC-grounded. If a circuit is grounded through a capacitor it is referred to as AC-grounded because only AC signals can pass through the cap to ground, DC levels are blocked. Whereas if a circuit is such that DC current can flow to ground, such as through a resistor, then it is considered to be DC-grounded. A classic example would be a non-inverting op amp configured with the divider feedback resistor connected through a capacitor to ground (AC-grounded), or directly to ground (DC-grounded).

    Irfanmrt,

    Next time try not to copy someone else's words !!!
    I guess members would prefer to learn your opinion on this issue ..

    Re: difference between ac ground and dc ground

    two seperate planes will be used for AC and DC ground during PCB layering. finally these two grounds will be connected trough a ferrite beed( inductor)
