Re: The Corona Virus Hoax of 2020 = 2021 "Vaccine" Shedding And Depopulation

Important news: travel restrictions lifted from February 25, 2022 From Friday, February 25, there are no longer any COVID-related border restrictions for travel to Iceland. All visitors are welcome, regardless of vaccination status, with no requirement to pre-register before visiting. There is no lo...

Re: Wet/dry circuit

I overlooked the non linear conditioning asked on Ec s. In my quick and dirty wave handing solution I was aware of some conditioning but thought it was going to be linear, easily implemented with op amps. I need a close look at the actual gain(Ec) transfer function to fully work out the panning usin...

Re: Wet/dry circuit

The THAT VCA: I recall it has two control inputs.
They are both linear giving Db gains. One input goes increasing the gain, the other one goes decreasing the gain.
If this is right a single linear pot could feed the 4 VCAs control inputs to achieve the wanted result.

Re: Component Matching Minimizes IM Distortion in the Demrow-Cohen Balanced Front End

I imagine there could be more subtle transistor parameters asking for matching.
Early voltage, capacitance,

Re: Component Matching Minimizes IM Distortion in the Demrow-Cohen Balanced Front End

Very interesting.

What about transistor matching, distortion wise ?

Re: A Differential Deboo Integrator to Servo Mic and Low-Level Preamps

In the conventional configuration, you do not need any matching. The important point, then, is the leakage resistor of the capacitor. This resistor gives the DC gain that comes in the residual error. ( A perfect integrator gives a zero error, because it has infinite gain ). One can calculate the err...

Re: Entropy

Amazing. My new tenant moved in jully 1. I was called this morning jully 5 for a toilet flush not working right, the push button doesn't pop back anymore. Was working perfectly right on jully 1 and days before while I was there fixing stuff. Turned out, it was a broken plastic bit next to another on...

Re: Entropy

Accelerated entropy, slob tenants at a place I rent. I spent days repairing goodies left by previous tenants. Well hidden when they leave, of course. A stuck sliding window, a shot of W40 freed it, but was sliding poorly and jamming half way. I spent hours to understand, finally started a major diss...
