How To Tell If Amplitude Is Positive Or Negative

how to tell if amplitude is positive or negative

Graph of Sine Function Singer
The amplitude and phase of the positive and negative frequency components are now very different. When shown as a polar diagram (Figure 10) we can see the two vectors quite clearly: one is approximately 3.94 at 127.5 o and the other is about 1.21 at 85.2 o .... It simply flips your graph upsidedown. Where it should have a positive amplitude, now gets negative and viceversa: For example: if you choose x=pi yo get sin(pi/4)=sqrt(2)/2 but with minus 2 in front your amplitude becomes: -2sqrt(2)/2=-sqrt(2): Graphically you can see this comparing: y=2sin(x/4) graph{2sin(x/4) [-11.25, 11.25, -5.625, 5.625

Amplitude and Phase of the Frequency Response Function

A negative sine function simply reverses this, going down, then up, then back to the start. An interesting quality of the sine function is that there’s no difference on a chart between a negative sine function and a positive function that starts in midcycle....
One is a positive frequency (target moving towards radar) and the other is a negative frequency (target moving away from the radar).This corresponds exactly to the complex representation of

How To Tell If Amplitude Is Positive Or Negative

2016-02-04 · I know that after 2π the motion will repeat itself so it will not really matter, but what is the conventional way to write the phase constant in the general equation of simple harmonic motion, x=A sin (wt+ φ) ; x is the displacement from the mean position, A is the amplitude, w is the angular frequency, and φ is the phase constant.

  • 2010-05-21 · no amplitude can't be negative. Amplitude is the distance from the median to the maximum or minimum. Hi Nsav8! According to http://en.wikipedia.org/wiki/Amplitude: Peak-to-peak amplitude is the measure of the change between peak (highest amplitude value) and trough (lowest amplitude value, which can be negative).
  • That negative number doesn’t make the amplitude negative, however! Amplitude is a measure of distance, and distance can’t be negative. You can’t walk –5 feet, for instance, no matter how hard you try. Even if you walk backward, you still walk 5 feet. Similarly,
  • So you know the limit on one side $\to \infty$ or $\to -\infty$ and would like to figure which one the limit tends to from the two. This is easy just note $\frac{\text{positive}}{\text{negative}}=\text{negative}$, etc.
  • Setting , we see that both sine and cosine (and hence all real sinusoids) consist of a sum of equal and opposite circular motion. Phrased differently, every real sinusoid consists of an equal contribution of positive and negative frequency components.
