oscilloscope sine wave

Summary 2--- multimeter measures the voltage of square wave and sine waveThe voltage of the square wave measured by the multimeter is the average and the sine wave is a valid value.The reason is: the multimeter uses the integral ADC, the results are averaged. ... Why is this

Use PowerPoint to make courseware, because it is easy to learn and easy to make easy to become the teacher's preferred tool. What we're going to talk about today is a demonstration of the sine wave in PowerPoint. The image of sinusoidal function is an important part of high school mathematics. But for many students, the content of this class is too abstract to be understood. Therefore, the mathematics teac

Sine Wave is the most single frequency component of a signal, because the waveform of this signal is a mathematical sine curve named. The courseware of dynamic demonstrating sine wave is made by using geometry artboard , and the working state of

I. Requirements: Requirements: Let the ball move along the sine wave. The constructor of the ball is as follows: The constructor of a spherefunction Ball (radius, color) {if (radius = = = undefined) {radius = 40;}if (color = = undefined) {color = ' #ff0000 ';}this.x = 0;This.y = 0;This.radius = radius;this.rotation = 0;This.scalex = 1;This.scaley = 1;This.color = color;This.linewidth = 1;}Ball.prototype.

[TM4C123 single-chip microcomputer practice] configure SSI and drive DAC7811 to display a sine wave, I have learned TM4C123 single-chip in the electric competition over the past few days. In general, combined with the official routine and reference manual, a good oscilloscope will be much more efficient. TI's SSI is actually SPI. First, familiarize yourself with
