Thanks guys!Technically it would be pulsed DC.
AC is generally where the voltage goes negative and then positive around some common point usually termed as ground.
But, that is all semantics.
If you're measuring with a DVM, you're getting some average reading that depends on the output swing and the duty cycle. If you really want to see what's going on, you need an oscilloscope. They're so cheap ($20 for DSO 138 at places like Amazon and Ali Expreds) these days that there's really no excuse for choosing to remain in the dark.The reason I ask is that I am trying to measure the output voltage and I get ≈ 4.95 vdc.
Depends on what kind of 555 it is. If it's a TTL version, then the high-level output is going to be about 1.5 V to 2 V below the supply voltage. With a CMOS version it will be much closer to the supply voltage. These are under no load conditions.Hi:
If I have a 555 astable circuit and a 5 volt supply, should I not get an output of
approximately 5 volts ac?
Thanks
