In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

This is an svg schematic of a 6502 microprocessor, consisting of a block diagram (bd.svg) and a circuit diagram (cd.svg). The latter follows the circuit of the original MOS Technology 6502 (as reverse ...

This audio mixer circuit schematic we propose here is built around four amplifiers, which are current controlled, all of them incorporated in IC SSM2024, produced by Precision Monolithics Inc. (PMI).

The heart of this digital volume controller DVC circuit is IC2 4067, 16-channel analog multiplexer. Because the 1kΩ has been connected between every input and output, the multiplexer can act like a ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
