Hi, can anyone tell me how to make a delay circuit using capacitors and resistors? I know that a lot of people have asked about this before, but I'm a bit confusabubled. The circuit is for an analogue audio equalizer thing.
Thanks.
Thanks.
It's going to be more elaborate than just capacitors and resistors - http://freecircuitdiagram.com/2008/08/19/analog-audio-delay-line-expand-your-virtual-3d-sound-space/.
A bucket brigade is a LONG string of capacitors, with a sample-and-hold circuit (generally an FET) between each one. With a clock signal, you transfer the charge from each capacitor to the next one in line. You then have to INTEGRATE (use a low pass filter) at the end to average all the charges together, and get an analog signal back out.Could any of you guys explain how your suggestions work, as I'm a bit of a beginner at electronics. Thanks a lot!
Do you know where I can get a BB without paying a load? They seem to be pretty much obsolete now.A bucket brigade is a LONG string of capacitors, with a sample-and-hold circuit (generally an FET) between each one.

The SAD512 uses 512 stages of capacitors and sample-hold devices. I don't THINK you want to build this out of discrete devices...but you could!
