Показать описание
In this video, which is a recording of a live-streamed exercise from the 'Electromagnetic Compatibility' module, we go through and discuss the simulation of the transfer function and attenuation of a low pass filter as a solution to Task 18 on filtering from our exercise booklet using the LTspice circuit simulator.

Note:
Unfortunately, I had to use a different laptop, so this recording is in in 720p resolution and not 1018p as usual. Also the audio quality of the original live stream recording was also very was also very poor due to the need to use the laptop's internal microphone. Auphonic was able to make it much better, although still far from perfect.
