There are many "tools" that are not fully understood. [Copy link]

There are many "devices" that I haven't understood thoroughly. Phase-


locked loop PLL, voltage-controlled oscillator VCO, low-pass filter LPF, high-pass filter HPF, adder, subtractor, multiplier, divider, accumulator, frequency detector, phase detector, integrator, differentiator, oscillator, mixer, latch, trigger, buffer, limiter, frequency synthesizer, detector, filter, frequency selector, amplifier, comparator, digital potentiometer, etc. Some are very clear, while some are only half-understood, or only know one thing but not the other. Although it is impossible to understand all of them, many of them are not understood at all.
