Over the last couple of days I've seen a few people mention how similar the ABC Australian logo is to the new Disney Movies Anywhere se...

A couple years ago I wrote some code to generate Harmonic Elimination PWM (HEPWM) waveforms in octave, which is kind of like Matlab.  Rece...

You may have seen that I've recently been analysing a toy that plays animal sounds .  It's nothing complicated, it just plays one o...

Today I'm going to have a bit of fun.  Once again the local supermarket has released a set of cards with pictures of animals on them fo...

I've been doing a series about how to calculate the switching times of harmonic elimination PWM waveforms and I thought it was time to ...

I've finally sorted out the code to generate PWM waveforms that you'd use to control an electronic device such as an H-bridge drive...

Harmonic elimination pulse width modulation waveforms can be used to control or completely dampen specific harmonics in a switched signal, ...

I'm looking into Harmonic Elimination Pulse Width Modulation (HEPWM) and it requires a bit of maths.  So although there isn't anyth...
