### How can prevent the source voltage from dropping when using a 555 timer

The root problem is not external inductance, it is an internal design flaw. The original bipolar 555 design is notorious for output stage cross-conduction. This is a condition where both output ...

### How can prevent the source voltage from dropping when using a 555 timer

The problem is most likely the lack of a power supply decoupling capacitor. When using a breadboard to prototype analog circuits I always put a 10uF capacitor on the supply rail.

### Increasing power of a standalone circuit board

At 7.83 Hz, a small magnetic dipole, the coil you see on this card, is extremely inefficient. The superpowers usually use 10s of km of overhead line together with a ground return to make an antenna to ...

### Calculate total harmonic distortion

$V_{1,rms} = 10^{\frac{dBv}{20}} mV$ Substitute this value to THD equation. $THD = \frac{\sqrt{V_{2,rms}^2+V_{3,rms}^2+V_{4,rms}^2+V_{5,rms}^2+...}}{V_{1,rms}}$ \\$THD = \frac{\sqrt{{(10^{\frac{...
