DC component means? Time Gap between positive and negative cycles

[danny davis]

What is DC component?

At my work , they say DC component is the "TIME GAP" or " Cross over" section between the positive and negative cycles at the zero crossing point when you have a push pull network

Is this Time gap or Cross over called DC component?

If the DC component is not zero and is +5 volts. The Positive cycle will END at +5 volts not at zero volts? The Positive cycle should END at zero volts having zero DC component

The DC component of any signal is its average value. Classic sine waves have an average of 0 volts and therefore no zero component. Circuits which operate off a single ended supply usually do not generate a negative going signal and therefore will always have a DC component. For DC coupled amplifiers with a single supply that is usually 1/2 of the supply voltage.

An amplifier which does not cleanly cross the zero is said to have cross over distortion:

Isn't that RMS?

Yes, but an AC sinewave from a push pull circuit will have an average of ? because it won't be 0 volts

Circuits which operate off a single ended supply usually do not generate a negative going signal and therefore will always have a DC component.

Isn't that DC offset? not DC component right?

An amplifier which does not cleanly cross the zero is said to have cross over distortion

Cross over distortion really means DC component right?
