QuoteWas it a problem because a voltage divider was used Yes it slowed down the edges like I said.

How does a resister "slow down the edge"?
Whereby the divider only adds to the harmonic?
QuoteWhereby the divider only adds to the harmonic? Not quite, there is capacitance all round but the resistor works with the capacitor to make a filter. For a discussion of simple RC filters see this page:-http://www.thebox.myzen.co.uk/Tutorial/PWM.htmlIt is the reduction of the number of harmonics not the addition that makes the rise time slower.
