Could someone explain me why I can't remove a DC offset from a square wave with a coupling capacitor ?
This square wave comes from the output of a 555 in astable mode, and the
peak to peak voltage is +5V from 0V to +5V, at a frequency of 1KHz, duty cycle is 50%.
NI Multisim says that the DC offset is +2.5V.
No matter the capacitor value I use, nothing happens, but when I try with a sine wave instead,
oh oh oh it works !
If you want the schematic just ask.
