Splet09. dec. 2024 · F = 1/ (2*pi*sqrt (L1*C1)) Depending on the frequencies you need to block, the values of the inductor (L1) and capacitor (C1) can be altered. For example, if mobile phones in your area work at 450 MHz, you need to generate 450 MHz with some noise to act as the blocking signal. Now the cell phone receiver will not be able to understand, … SpletThe present invention relates to a spot killer circuit, wherein the drive from the horizontal drive circuit to the high voltage generator circuit is stopped to stop the operation of the …
