Interview announcement with Mike Engelhardt - Inventor of LTspice and now QSPICE Thanks to all those who watched my earlier announcement for QSPICE - this brought attention to the channel and this interview became possible. LTspice is dead and QSPICE is born: https://youtu.be/u3xkLTgoQec ... https://www.youtube.com/watch?v=a6hQeTUFV8Q

This video I'll show how adding a 2 way crossover affects the signal by looking at the spectrum with the PicoScope 4444 Oscilloscope. The name of the video is: 'Class D Amplifier meets 2-Way Speaker Crossover'. The Class D amplifier uses 2 of the TDA8954, one per channel.

This video 'Orchard Class D Amp with GaN FETs at 100 Watts, I'll show the Starkrimson Class D Amplifier module with GaN FETs. I'll run the power of this Class D amplifier up to 100 Watts and we will look at the temp and effeciency at 100 Watts. We will also look at the (spectrum) FFT and THD of tthe Starkrimson Ultra module at 100Watts. These are loaned to me and I'll have to return them, but I might have time for one more video.

This video is shows how to Graph Inductor Impedance with a GW Instek Scope. An Oscilloscope with the ability to do a Bode Plot is great for graphing Impedance. The GW Instek is a great scope to do this. You can support this channel with this link to Patreon - I really do appreciate your support?
