In trigonometry, the period of a function refers to the distance of a function's wave. Learn how to find the period of a trig function by exploring...
What is a Function?Watch the video for a quick explanation of functions vs. non-functions:Can’t see the video? Click here to watch it on YouTube.A function is a type of equation or formula that has exactly one output (y) for every input (x). If you put a “2” into the ...
Within each period of the carrier, the duty ratio of the PWM pulse is proportional to the amplitude of the audio signal. In the example of Figure 7, the audio input and triangular wave are both centered around 0 V, so that for 0 input, the duty ratio of the output pulses is 50%. ...
To capture the true shape of the signal, you need a high-bandwidth scope. For instance, a 10 MHz square wave is composed of a 10 MHz sine wave and an infinite number of its harmonics. To capture the true shape of this signal, you must use an oscilloscope with bandwidth large enough ...

Some holograms even appear to move as you walk past them and look at them from different angles. Others change colors or include views of completely different objects, depending on how you look at them. Holograms have other surprising traits as well. If you cut one in half, each half ...
(the number of waves passing a point per second, related to pitch), time period (the time it takes for one complete wave cycle to occur), and velocity (the speed at which the wave travels through a medium). These properties intertwine to craft the unique signature of every sound we ...
Ideally, an oscillator should be able to produce a specific set of stable frequencies over a specific time period. However, in the real world, there are always small, unwanted amplitude and phase fluctuations present on the signal. These phase fluctuations, or jitter, can be seen spreading...
I'm new in this forum and also a newbie concerning the handling of a microcontoller.So in advance, please excuse my diction.I'm using a MC9S12C128 and I'm trying to change the dutycycle of the PWM signal every period, in order to generate a sine like waveform (of...
10. Drift Drift—or minor changes in a signal’s voltage over time—can be tedious to diagnose. Often the change is so slow that it is difficult to detect. Temperature changes and aging can affect passive electronic components such as resistors, capacitors and crystal oscillators. One problemati...
