... The term 'op-amp' was originally used to describe a chain of high performance dc amplifiers that was used as a basis for the analog type computers of long ago. The very high gain op-amp IC's our days uses external feedback networks to control responses. The op-amp without any external devices is cal ...

... A modern AC electric machine is usually driven by an inverter using PWM control to ensure sinusoidal phase currents with a low total harmonic distortion (THD). For an increasing fundamental frequency, fewer pulses are created for each fundamental cycle and six step operation, another power electro ...

Bode plot
In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude of the frequency response, and a Bode phase plot, expressing the phase shift. Both quantities are plotted against a horizontal axis proportional to the logarithm of frequency.
