Youssef Touil, to learn how, exactly, this passive loop works. Youssef was the guy who experimented with several loop designs and ultimately inspired me to build this loop to pair with hisHF+ Discovery SDRand theSDRplay RSPdx. “The main characteristic of this loop,...
To compensate for the nonlinearity, HF probes tend to shunt the input of a scope with a very small capacitor and a series resistor right at the BNC. This serves to move any nonlinearity into a higher frequency region, outside the intended range of the probe, without causing severe overshoot...
up to infinity. To correctly amplify a mixture of sinewaves with frequency up to infinity, you need of course an infinite bandwidth. There's nothing special about the input amplifier of a scope, except that it is a very sophisticated and very fast one. In your case, where you limit ...
In the old days, the most common way to apply AM modulation was to modulate the high voltage to the plate of the tubes, using a transformer and a powerful audio amplifier. In low voltage solid state circuits, you can still do it using transformers, but you can also use series transistors...
