I would like to build, from passive components, a single stage variable bandpass filter for a white noise source that operates across a range of about 100Hz to 10KHz. I realize the Q will be extremely low, but this is just a starting point that I will add to.
Can someone please advise regarding...
Hello again,
I have some concerns about how many EMI-filters that I should use for my AC/DC charger?
My charger is operating as a low-power charing (950 W).
I have read in in different articles, that some charger have only one input filter, and in some other cases they also have a output...
Do anyone how to draw typical EMI filters in LTspice? I have read in different articles on the internet,
and it seems they differ in design time to time. I have attached my file so you can see how it looks like.
I am suppose to have another filter my DC/DC converter as well.
I have been tasked with designing and building a device that will use a .4V Peak to Peak amplitude voltage source to power 5 IR LED's in parallel. I have attached my design schematic, which includes a low pass filter amplifier with a cutoff frequency of 120Hz and a gain of 101 (though the opamp...
Hello,
I am creating a PWM signal by comparing a sine wave (50Hz) and a triangular wave arrier (10kHz) ,in ordem to control a full bridge inverter.
II had been try filter this pwm signal to obtain a sinusoide, with a LC filter. I use this equation to find a cut-frequency of the filter (and...
I've searched the Web, but I can find no mention of using a common USB antenna analyzer (such as the Mini60/SARK-100 with software) to graph the band-pass of an HF filter. To me, it seems like a no-brainer, but perhaps I'm missing something critical here:
Antenna analyzer-->LPF/HPF/BPF...
