What does Ethernet 100BASE-T signal look like? Below is a typical MLT-3 waveform From here: Power over Ethernet (PoE) injects a DC bias of about 48V onto the signal pairs to carry power to the far-end device There are two modes for this: Mode A, which uses the center tap of the transformer, or Mode B, which uses the unused signal pair Mode ‘A’: Mode ‘B’: From here:
operational amplifier - Why does my op-amp circuit output a rectangle . . . I'm trying to simulate a non-inverting voltage amplifier It is supposed to generate a similar waveform but when I use the oscilloscope I see that the wave is a rectangle not a sine wave Can someone explain what is wrong? The first picture is wrong I know but it is just for experimenting the op-amp
DO-160 indirect lightning requirement confusion For DO-160, there are Waveform 3, 4, 5A B, and each waveform has its own requirement Can some please give me an example on how to check if the tvs diode complies with each waveform I am also worried about certain phrase such as pin injected, cable injected, and multiple burst, single burst I don't know what is going on Please help out
waveform - Equation for the average power of a signal - Electrical . . . The "area under the curve" is the general way to compute the average power for any waveforem x (t) The specific formula with the 1 2 and the 1 3 happens when you plug this specific trapezoidal waveform into the general equation
BLDC motor waveforms - Electrical Engineering Stack Exchange The diagram below shows typical timing of the drive waveforms sent to the switching devices (eg MOSFETs) When the motor is synchronized the voltage waveform across each phase should be a trapezoid shape, as the voltage slopes up and down between activation of each switch Therefore you don't need to modulate the PWM in a sine wave
Sine wave shows up on oscilloscope but keeps moving I'm fairly new to electronics and new to using an oscilloscope I followed a youtube video to setup a sine wave using an Arduino Uno and a capacitor to detect on my Tektronix 2235 https: www you
