Electrical waveform analysis

waveform analysis

Waveforms and what they mean ...... a wave is a graph of Voltage vs Time Here are some of the very important wave forms that you will see many variations of. Wave forms tell you about the magnitude of a value such as voltage or current over time.
see >>> Hypolyte Pixii's original DC generator	DC generator creates PDC due to commutation (reversal) of sine wave at commutator
see >>> another AV demo	AC generators produce a sinusoidal wave form described as V = sin*Vmax T = time of cycle (Period) (s) F = 1/T (frequency) (Hz)
	- 3 phase systems are in use everywhere - they produce 3 120 degree out of phase lines Tesla

	Sine Wave tides, planets, music, all follow sinusoidal rhythms
	V_rms = V _max X 0.707 more about RMS>> V_p= V _max V_pp = 2V_max = 2V_pp
	Period is the time of a cycle a cycle is the time between 2 similar adjacent points on wave
	half wave PDC results from a one diode rectifier note that half the original sine wave is missing is missing
	Full wave PDC results from a 4 diode rectifier
	capacitative filtering "smooths" PDC
	a larger capacitor provides greater filtering
	a combination of waves results in complex analogue waves
	triangle wave
	analogue means the same as analogue waves always look similar to the original signal digital waves are square waves that often use digital encoding to process information
	square wave used in digital electronics ON/OFF electrical state HI/Low digital state 1/0 digital number binary states
electrical picture of the cardiac cycle	your heart is a muscular pump activated by a biological electronic oscillator when a heart looses rhythm a medical defibrillator built around a capacitor can start normal rhythm by delivering a shocking pulse of electrical energy electricians should avoid electrical current through the chest as this can disturb the heart's natural rhythm keep one hand behind your back!
