Q is a dimensionless number. It represents the ratio of the maximum energy stored to the power loss in a system at a given angular frequency, rather than the inverse (DF).
I now hope to cover the comparative advantages and disadvantages of both mechanical and electronic potentiometers.
A growing number of companies are developing products for military purposes or for space exploration. They are being helped by NASA, ESA, SpaceX, and others.
Did you ever wonder how "they" did that, especially when we can only think of doing it the new way with our advanced technologies?
The question that arises in the design of a simple PWM DAC is what the low-pass filter pole frequency should be relative to the PWM frequency. This question is addressed by deriving the design equation.
