Hello
I am made a simple 555 timer producing 10V pulses as per the website
**broken link removed**
The circuit diagram from this website is attached below.
I need pulses from 25V to 35V. Therefore i connected a 25V DC supply in series with 10V 555 timer output.
While testing the circuit, i found two problems.
1) At the instant the pulse transition occurs from high to low or vice versa, the power supply for driving the 555 timer also fluctuates. How to avoid this problem? Why does it occur?
2) The transition is more like a ramp from 25V to 28V and then to 35V. How to make it abrupt transition?
Thanks
