The frequency modulator has an extra capacitor (4d) switched in and out of the resonant circuit (jb, 4c) of an HF oscillator (4) when the alternating voltage passes through zero. The capacitor has the same effect as switching between two separate oscillators but does not have the ...
The manufacturer recommends a large (1000μF) capacitor across the power supply and a 300-500Ώ resistor inline with the data pin. With the circuit working on a breadboard I created a PCB design which includes these components plus some screw terminals to connect the NeoPixel strip and a ba...
The temperature compensatible circuit for a quartz crystal has an additional capacitor (Ck) coupled in series with the quartz crystal and whose parameters are chosen so that the quartz crystal frequency is compensated in the opposite direction to its tendency to change with temperature. The ...
Changing to the brake position the direct supply to the motor (11, B) is interrupted, and the thyristor circuit (12) closed. The thyristor conducts half cycle current impulses until the capacitor (C1) is charged. Gate pulses are then blocked. The current impulses give inductive braking. In ...
