Coaxial Cable Losses & Velocity Factor
A short film to illustrate RF losses in coaxial cable and the effect of Velocity Factor to produce physical lengths much shorter than the calculated electrical lengths. Intended for use as part of the Bath-Based Distance Learning course for the UK Advanced.
Harmonics & Low Pass Filters
Great Video on Harmonics & Low Pass Filters
Scopes & Rectifiers
Made in support of G0FUW Advanced Distance Learning Course. This part shows basic oscilloscope features and how diodes rectify AC.
SCOPES & RECTIFIERS 2
Made in support of G0FUW Advanced Distance Learning Course. This part shows how smoothing capacitors and voltage regulators smooth out power supplies.
Short video to demonstrate amplitude modulation waveforms. Intended to be used a s part of distance learning for the UK Advanced Radio Communication examination but may be of use to others.
