Decoupling Capacitor Placement in PCB Layout
This means you''ll need to place the decoupling capacitor as close as possible to the IC''s pin. If you''re designing a multilayer PCB, place the capacitor beneath the component''s pad. On a single-layer design, the capacitor is placed near to the pin and routed with a short trace. Place decoupling capacitors close to voltage pins.
Replacing Through Hole Electrolytic Capacitors
Now you can remove the electrolytic capacitors. There are 2 methods you can use: 1. Heat one capacitor lead and lift the capacitor lead slightly out of the board. Keep doing this until the capacitor is free from the circuit board. 2. Desolder both legs of the capacitor, then pull the capacitor out of the circuit board.

Envelope detector
Envelope detectors can be used to demodulate an amplitude modulated (AM) signal. Such a device is often used to demodulate AM radio signals because the envelope of the modulated signal is equivalent to the baseband signal. To sufficiently attenuate the frequency of the carrier wave frequency, the cutoff frequency of the low-pass filter should be well-below the carrier …
Choose the cutoff frequency from the sampling rate
It also estimates that you might be interested in a baseband of 8 Hz (just a guess on my part). Given that 8 Hz is 12 Hz lower than the Nyquist frequency (20 Hz), the lowest frequency that can cause aliasing is 32 Hz (12 Hz above Nyquist). The lower picture shows how you might implement an anti-alias filter. That filter will attenuate artefacts ...

How to use hot air gun to remove components without warping
Using a temperature of 330C, I seem to be able to get small SMD resistors and capacitors off fairly quickly (ICs take a little longer, but don''t seem damaged.)

How to remove capacitors that are glued down?
I find it very difficult to remove the solder between the lead and the pad where the lead is bent at a 90 degree angle. Then when I go to wiggle on the cap gently to remove the cap, the glue that hold it down forces me to wiggle a little harder and the added resistance of the glue make it hard to tell if there is still some solder under the lead.

To remove AC noise, a bypass capacitor is placed in parallel with a resistor. A capacitor offers high resistance to low frequency signals and less resistance to high frequency signals. As such, low frequency DC components use the resistor path while high frequency AC components are shunted to ground through the bypass capacitor. This yields a ...
