What is the difference between the terms wave, waveform, and signal? A waveform is a representation of physical quantity such as voltage or a current over time If this physical quantity carries information then it is a signal In practice, however, the terms signal and waveform are often used synonymously
What exactly are harmonics and how do they appear? This is called Fourier analysis (if the original waveform is repeating) or Fourier transform (for any waveform) In case of a repeating waveform (like a square wave), when you do Fourier analysis you find that all the sines that compose the waveform have frequencies that are an integer multiple of the frequency of the original waveform
Waveforms of BLDC motor - Electrical Engineering Stack Exchange The waveform on the first picture is correct The hall effect devices are used to provide the timing to switch phases You cannot swap phases without changing the halls; otherwise the motor phases will switch at the wrong time, and the direction of the motor rotor's torque change to the wrong direction when the hall signal change
rf - What are the waveforms of radio frequencies? - Electrical . . . What is the waveform of radio frequencies? I thought they were sinusoidal; am I wrong? I started to wonder about radio frequency waves at the time (two years ago), if they were digital, because all systems are digital, but the problem was that radios were being used in World Wars I and II, and even before At that time, electronic devices were
Sources of Harmonics (Odd and Even) The question of "sources of harmonics" is sort of a chicken and egg question You can generate a waveform by combining harmonics, or you can generate harmonics by producing a waveform Usually, the second meaning is what is used The harmonics are generated by whatever process created the waveform
What does Ethernet 100BASE-T signal look like? 100BASE-TX, the most common 100BASE in use today (and what's likely being used in your setup), uses a PAM-type variant called MLT-3 Below is a typical MLT-3 waveform Power over Ethernet (PoE) Power over Ethernet (PoE) injects a DC bias of about 48V onto the signal pairs to carry power to the far-end device
dc motor - DC Machine Ouput Voltage Waveform - Electrical Engineering . . . (B) is a good candidate for the resulted waveform when the brushes are in positions A and B on the commutator The basic place of the brushes should give full voltage and minimize the sparking Just when one lamel leaves the brush, another enters and add the same voltage to the series connection which is dropped off at the same time
What Does 8 x 20-µs and 10 x 1000-µs Mean in Surge Testing Terminology standardized transient impulses (or sometimes it's called a waveform) But what does it actually mean Why is there a multiplier in front of the time unit? The quoted line above is constantly mentioned in surge testing document But no where in the document does it mention what is the meaning of it Most Google search results point to Datasheet
How to use a CSV file from an oscilloscope for further analysis How to plot the real scale waveform data? Do I have to multiply it with vertical scale? And what about the time? What to do if I want to plot the waveform data in the time domain? Since there's no time data and all I have is the sample period, horizontal scale and position here's the waveform from the oscilloscope display Thanks!!
What can reduce overshoot and ringing on a simple square wave pulse . . . And the waveform output: In particular, the rising edge of the square wave has a substantial amount of overshoot (about 200mV over 500mV peak) and ringing It is easy to make it worse, by physically touching R1 See edits for correct info
