How to get started with analog electronics?
You probably should examine opamp circuits, first DC, than AC. They have the advantage that the theory is relatively easy and they often behave as predicted. Using these learn to...

A bunch of 10ohm resistors on schematic - why?
Thanks for the info. I experienced that faster ICs are often more susceptible to latchup and latchup often can be reckognized by high supply current and often heated IC. Probably...

High Voltage Measurement
One problem with a 100MOhm resistor is its parasitic resistance, you have to compensate it, probably even at 10kHz (been there, done that) a reliable 100:1 probe often works...

Convolution is what linear time-invariant systems do.

A bunch of 10ohm resistors on schematic - why?
You said the circiut dies after a short time. What happens ? Does the Fifo-buffer get hot ? draws it more current ? If so, you perhaps have latchup-problems due to voltage over/...

DC-DC 12V-1kV
I have a Anita Sumlock (dismanteled) here, contains also a Dekatron, many thyratrons, and a lot of nixies, and in fact, there is one transistor in it ! http://www....

DC-DC 12V-1kV
I am confused: Does the TLV5625 really have an internal Vref ? The headlines in the datasheet say so, but I only find a description for a VREF input in the following sections. :...

how to program N82S23
with 50ns access time you could built something like programmable logic. That time EPROMS probably hat 1000ns access time. And it were 32 Bytes at all!

Webinar AVR/SDR see and hear me
Hi Jim, It would be interesting to test whether you could receive WWVB at 60kHz and lock the VCXO to it using the concepts. Since I tested the receiver using MSF (UK) at 60kHz it...

DC-DC 12V-1kV
That looks really good! Congratulations. My scope-clock is also very sensitive to voltage fluctuations. I think the deflection amps are sensitive. But when I run the clock I do it...

High frequency output PWM - how make good resolution of PWM?
You may use a DDS to switch the pwm-time between two values, for example with 0.2 probabilty using 10cycles and with 0.8 probability 11 cycles makes 0.2*10+0.8*11=10.8 cycles But...
