i figured i could use pspice to figure out some of the value details.

yes, and yes. i understand the filters, i plan on using active filters with op-amps probably... and for the output i figured leds and resistors... but other than that, I am not really sure.

also a fairly important feature would be low-cost.

could you explain perhaps the purpose for each circuit? I understand the filters to separate the different frequencies, but not the rest

well, i understand the basics... I've completed a circuits analysis class, linear signals and systems, digital electronics and others, and I am currently in a random signals class, power systems analysis, analog electronics, emag, and this radio lab. See, the main project is to build a radio...

ok... Yes, well, in that case, can someone describe to me a way in which to display the signal on the LEDs? I can create the high and low pass filters... I was just curious if there are resources that I can use to figure it out.

I am working on a project for my electrical engineering lab class, and am interested in learning how to build a led spectrum display. I'm looking at very basic. I want 3 sets of LEDs, one for the high, one for the mid-range, and then one more for the low. Any clues where i can find a design...
