We had to build it for our ECEn 212 lab.
It’s extremely long labs like this that are the reason I haven’t been blogging much lately.
28 resistors, 6 Pots (variable resistors, 1 of which is logarithmic), 16 capacitors, 2 inductors, 12 operational amplifiers and a bunch of other wires I don’t want to count.
Basically it sends the low frequencies to the woofer, the high frequencies to the tweeter etc..
The white and black things that look like tubes of tape is just copper wire wound around a tube (an inductor)
