Part 2 of the AC Basics tutorial series. What are phasors and doing phasor addition. In-phase, out of phase, and leading and lagging waveforms. Phi vs Theta phase angle. Leading into complex numbers in Part 3. 00:00 – AC Basics Theory 00:40 – How an AC waveform is produced 01:37 …

A tutorial on how to read timing diagrams. An essential skill for designing and understanding digital logic, FPGA and microcontroller designs and datasheets. Forum HERE Podcast: Download

Circuit building block time. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator. Whiteboard theory and then some bench demonstrations and experiments. Plus a twist at the end that proves that the “Capacitance multiplier” is perhaps one of the most mis-named circuits …

An in-depth practical visualisation of how bypass capacitors work at both high and low frequencies. Bulk decoupling capacitors vs bypass capacitors. Capacitor placement and types are tested and the results examined. How package inductance can have a large effect. Loop area and what is means, it’s impact on EMC emissions, …

Fundamentals video explaining the difference between voltage, power, and energy. The difference between Power & Energy is probably the most misunderstood and misused terminology in engineering! Forum HERE Podcast: Download
