Analog Filters (Part 1)

Playlist (with all related videos): • Electronic Circuit Des...
In this tutorial we focus on the very basics of passive analog filters. The most simple analog filter, a passive low pass filter, is described by the means of an RC circuit. In order to understand all it's implications, a simple capacitor, as well as some important descriptions of its behavior, like the bode plot and the phasor diagram, are elucidated.

Please continue to make this kind of videos ,they are of great use.It helped me to clear my interview for design engg role.Thanks a lot sir

[@ife.tugraz]

Thank's a lot! We are continuing on our new channel:

Very good explanation. Keep putting such good content related to electronics and circuits.

[@peterlimwijaya9442]

amazing works man !

[@sisami2109]

Amazing work, thank you !

[@michaelfuchs441]

Thank you! I hope that we can do another two videos on active filtering by end of February.

[@branton0]

Good stuff

[@ADITYASHARMA-zl5mt]

Amazing video plz make more videos related to electrical engineering

[@michaelfuchs441]

We've got a bunch of them and a lot more are coming at the beginning of January.

Sorry but in Minute 12:40 you show how Zin is built from Zc and R graphically in the phasor Diagram. But then you just say in the Voltage divider equation Zin equals R+Zc? NO way! Pythagoras would not be amused!! This is so confusing, where is Laplace transformation?

[@michaelfuchs441]

I'm sorry to confuse you. I know I oversimlified here. Z_C and therefore Z_in are always complex values. If you want to calculate only the magnitude of Z_in, of cause you will need to use pythagoras. In our calculation, we assume that we are dealing with complex values (magnitude and phase). Therefore technically the plus sign is correct.

[@SE-144]

@@michaelfuchs441 oh, it makes sense because phasors by nature introspect vectors, where Z_in is the resultant vector. Is that right?

[@michaelfuchs441]

@@SE-144 Yes, Z_in in this case is a resultant vector.
