CONT> Trianglewave to PWM waveform
Posted 05-11-2011 at 02:50 AM by hobbyist
Hi,
This is a continuation of the original squarewave to triangle wave in the series of designing a PWM circuit using all discreet components
http://www.youtube.com/v/KnFV7qTVJB0?hl=en&fs=1
This video shows how the amplified triangle wave is fed into the volt. level detector circuit (schmitt trigger) and the resulting output of the waveform needs to be conditined further by using a voltage diode clamper, to get a zero ref. voltage.
Than the waveform is easily adjusted in its width. While frequency and pulse voltage amplitude remain fairly stable.

Hello,
To have a stable output, you will need a clamper.

Hi Bertus,
The clamper was introduced in the last part of the video.
But all the same, thanks for the link.Posted 05-12-2011 at 09:12 PM by hobbyist
