00:06This video will demonstrate the creation of a square wave and triangular wave oscillator circuit, which is a complement to a square wave oscillator circuit.
00:11In addition to another circuit with an SCR or TRIAC, the main applications can be given,
00:17In motors, pulse width modulation is a technique used to regulate
00:21the rotational speed of electric motors. As its name indicates, by controlling, a
00:27high moment, on or powered, for this we need an electrolytic capacitor
00:32of 0.22 microfarads, grounding, and two 220 kilo ohm resistors, an amplifier
00:43To operationalize the F402 ECN, we also added another 10 kilo ohm resistor,
01:09We also added another 220 kilo ohm resistor, performed the same procedure, and now we have...
01:19an operational amplifier the F402 ECN, also another capacitor of 0.22 microfarads, also
01:27a 5-volt DC power supply with both negative and positive terminals
01:32C, we will arrange it thus in the second operational amplifier,
01:48We can add another operational amplifier, the F402 ECN; in this third element we also add a
01:565-volt DC negative current power supply, we added a ground,
02:07and an interactive DC voltage signal generator, at 5 kilovolts,
02:21Now we make the connections,
02:32The amplifiers are inverting summing units,
02:35und ropa dua fiend darum,
03:03Like the rupture selfies in Wahrarest La Rada and Mala Jacka, much of the rupture interest
03:18Now we make the oscilloscope connections; we have the probe connected to ground.
03:31Channel 1 is connected to amplifier output 3.
03:39Channel 2 is connected to the output of amplifier 2.
03:48Channel 4 is connected to amplifier output 1.
04:03In the simulation we already have the different waveforms, both square and triangular.
