    What are these High frequency Artifacts from or cause by?

    In Clock,timer, pulse generator circuits

    There is ripple on the High state

    There is High frequencies between the pulses

    If at the start, then transients or transient response. If in steady-state, then interference, bad design.

    Are there interferences? what kind to cause this?

    what about the ripple riding on the logic High State?

    Take a look at the pictures and what do you guys think it is?
