Hi my name is chittaranjan. I need a waveform with power on as follows



1.HIGH for 1 sec
  1. LOW for 2 sec
  2. HIGH permanently

Please help me obtain this waveform without using any microcontroller


Read in fixed font or M$ Notepad:

| | VCC | + | +| | --- | 1uF--- | | |\\ ___ | .---o---|H>O--|
