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, and how currents flow in ground planes is demonstrated
Some quick extra tests on the 6 of the 14 pocket multimeters from Part 1
Which meter *won’t* survive testing?
14 pocket multimeters from $8 to $65 are torn down and compared for feature set and build quality.
Ranging in price from $8 to $65, which one is the best in each price category?
Part 2 coming tomorrow.

What does the UL type approval compliance logo on consumer products mean?
What about TUV, ETL, GS, CCC and other marks?
Dave breaks down safety standards and compliance marks.
Can a product work without ANY bypass capacitors?
Dave finds out by “Muntzing” the Gigatron TTL computer.
Lots of interesting talk on bypassing, grounding, probing, signal integrity, ground loops and noise and crosstalk.
