So, filter 4. I wonder how many different filters I will end up making. hmm.. well, probably as long as I’m able to come up with interesting designs I’ll keep going. For this one, I know of only one single filter in the audio world which uses this topology, butContinue Reading
Third batch of the old school VCA has landed. A few minor changes have been implemented in the design to get rid of the annoyances I encountered using them. And since I’m the C-level executive of S&C, whatever I say goes! I also empty the trash bin and mop theContinue Reading
For another project I’m working on I needed a multimode filter. For the uninitiated, its a single filter that has a HP/BP/LP function, and does it all simultaneously. An OTA design is fairly common for this type of filter, so that’s what I did. Now, there are a zillion differentContinue Reading
I accidentally, a filter. Who knew that could happen. Maybe I’m picking something up about that whole electronics stuff after all. One can dream. But here it is and I proudly call it VCF-2, quite original, I know. But I ran out of cool sounding names a while back soContinue Reading
There’s that saying that you’ll never have enough VCA’s in your modular system. IMHO you never have enough of anything in a modular, but let not digress. VCA’s are useful little buggers that you simply can’t do without. I’ve build a variety of them in the past, mostly incorporated intoContinue Reading
You cannot build a modular without any mixer modules. I’ve made quite a few mixer modules by now and I noticed I hadn’t put anything up online. So, I’m rectifying this oversight with this post.Continue Reading
