Hello everyone,
Just liek to know if it is a normal thing that at LOW frequencies ( 15-25 Hz) that the output of a 555 timer is not exactly a square wave. At higher frequencies I get a perfect square wave (say between 50 and 300Hz). But at lower frequencies, the voltage when get to high, slowly decreases until the output of the 555 turns off. So usinf a 6v supply, instead of getting 6v high 0v low. I get 6v high,
5.99v, 5.98 ... 5.89, (there is a small slope at the high) then it goes low to 0v. I am using 50% duty cycle.
I hope I was clear enough thank you,
