CONT> Trianglewave to PWM waveform

Hi,

This is a continuation of the original squarewave to triangle wave in the series of designing a PWM circuit using all discreet components

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.
