In a normal heart it is pointed (in three dimensions) mostly to the left, somewhat back, and down.

Adding a DC source to a square wave signal?
Adding a DC source to a square wave signal will alter the base line of the wave without changing the peak-to-peak value. For example, if a square wave has a +4V baseline and a +2VDC source is introduced, the resulting square wave will have a +6V baseline. This of course will also affect the high and low peaks of the signal. Assuming that our example has a high peak of +9V and a low peak of -1V (with a total of 10V peak-to-peak), the added +2VDC source would result in a high peak of +11V and a low peak of +1V; however, the total peak-to-peak value remains unchanged at 10V peak-to-peak.
Are peak-to-peak and rms voltage measurements the same?
No, the peak-to-peak voltage is 2sqrt(2) times as much as the rms for a pure sine-wave.
What is the rms of square wave voltage?
This depends on the duty of the square wave - if it is 50%, then it will be 1/2 the peak. If it is 33.3%, then it will be 1/3 the peak.
4.0Vrms sine wave equals peak to peak voltage?
4volts x 2.8 =9.6 v
The rms value of the resultant current in a wire which carries a DC of 20A and a sinusoidal ac of peak value 20A is?
From your description, this sounds like it is a sine wave offset to 10A, so the peak is at 20A, and the min is at 0? For this case, you have 10A DC (RMS) wave and a 10A Peak - neutral AC wave; The RMS value of the AC wave is: 10/2*sqrt(2) = 3.54A. So the RMS amplitude of this wave is 13.54A.
What is the peak of a sound wave?
The peak of a sound wave is the instant at which the particles in the conducting medium are displaced farthest from their rest position. Note that the peak ... or any other point in the wave ... moves through the medium, at the speed of . . . . . wait for it . . . . . sound !
Is amplitude a vector or scalar quantity?
Yes, because amplitude is the maximum displacement of a wave from its rest position and displacement has direction and it's a vector. hence, amplitude is a vector. That is a bit like saying a weigh scale is a vector, because it goes up and down as you get on and off it. As with weight, pressure, etc, amplitude is the scale of wave magnitude against which particular waves are measured. Frequency is the vector, because you are measuring from one peak to the next, so the "length" gives it "direction," ie. a vector.
What Is an accurate description of the amplitude of a wave?
The amplitude of a wave is the top or bottom half of a wave. The middle of the wave is considered the "zero position" so the top of every peak tells how much energy is left in the wave.
What is a description of the amplitude of a wave?
The amplitude of a wave is the top or bottom half of a wave. The middle of the wave is considered the "zero position" so the top of every peak tells how much energy is left in the wave.
What is the maximum distance the particles of a medium carrying the wave move away from their resting position?
A wave's ___________ is a measure of how far the particles in a medium move away from their normal rest position.
Maximum distance a wave vibrates from its rest position?
The maximum distance is called its peak. The distance between the wave's positive and negative peaks is its amplitude.
What trait of wave is described by its wavelength?
The distance from one wave peak to the next wave peak
What trait wave is described by its wavelength?
The distance from one wave peak to the next wave peak
The is the greatest distance that particles in a medium move from their normal position when a wave passes.?
When measured, this distance (from normal to peak) is considered to be 1/2 of the amplitude. Amplitude is defined as the peak-to-peak distance.
How do you get a wave's frequency?
Measure the time for a wave to pass a given point- peak to peak. The number of complete peak-to-peak waves per second/minute is the frequency of that wave.
What trait of a wave is described by it's wavelength?
The distance from one wave peak to the next wave peak
What does peak and trough mean?
Peak means that from the middle of the wave to the top of the wave Trough means that from the middle of the wave to the bottom of the wave
