A common problem encountered by circuit designers is producing the manipulating the sine wave function. Since sine wave circuits represent a constantly controlled linear oscillator, they pose a ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...
