No. Features: Color: Blue; Working voltage: 5-12V Furthermore, the amount of flux linking any one winding coil 18 is controlled by providing a magnetic path of equivalent reluctance for the nonlinking flux. The circuit is very basic. Pulse Wave Generator A pulse generator allows control of the pulse which are repetition, pulse width, pulse amplitude and pulse width. If the pulse type is pcb // Then, the counter is increased by a step until it reaches 360 float rads = (angle * 71) / 4068; The frequency is dependent on the output square pulse of the IC. Winding slots 62 extend from the outer periphery to the inner periphery of the disk and have their axes located along radial lines. 6a, 6b and 6c illustrate the flux which links and which does not link any one coil winding as the rotor is moved relative thereto. This arrangement substantially maintains a uniform reluctance I in all magnetic circuits. : In generator constructions known heretofore, some of the flux which was not to link the coil winding did link it because the magnetic path for the linking flux was of less reluctance than theone for the nonlinking flux. I have an application that requires a square wave pulse with the following characteristics: frequency = 10-200 Hz width \\geq 20 \\mus risetime < 100 ns Additionally, the application requires a very flat top to the pulse.
