Hey guys,

For one of my electronics courses, we've been assigned to create an effects module - something similar to a synthesizer effect.
There will be a input signal (probably from an oscillator circuit) into this module.
What I need to do at the moment is create a basic block diagram of the signal processing that takes place in the effects module.
I was looking at (but not limited to) doing something along the lines of a reverb effect.

I'm fairly confident with my electronics knowledge, but this has got me stumped (for the moment).

Perhaps something like:

Input signal -> copy signal -------------------------------> sum -> output
. . . . . . . . . . . . . . . . . . -> delay -> attenuate (tail off) -> sum

Thanks for any help
PS: No digital circuitry is allowed in the effects module

 

What has got you stumped? What reverb is? Conceptually how it is accomplished? Physically how it is implemented? What?

What have you found from your research into reverb?

 

You will need to know what the following circuits and terms are

Mixer
Envelope shaper
Signal attack
Signal decay
Spring line (if you must have non digital reverb)
Transducer

If you do not know what these are, look them up, ask for help if you need more.

 

You can make a 'ring modulator' mixer with just two audio transformers and 4 diodes.
