ac ground
Whats the difference between AC ground VS DC ground?
How do u know which is AC ground and where is DC ground?
To add more GAIN we use a "bypass capacitor" in the emitter or cathode, but the bypass capacitor is to DC ground, i don't understand how AC signal can not go to DC ground but get more Gain from the AC signal
Someone told me that the + symbol of the rails is AC ground and the ground symbol is DC ground is this true
But how can AC signal not go to DC ground but get signal GAIN from components like bypass capacitors tied to DC ground
RULES
1.) 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.
2.) 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.
3.) capacitor to ground (AC-grounded), or directly to ground (DC-grounded).
