From trigonometry, we know that the period of a sine wave is 360 degress. 1 µHz to 50 MHz sine wave, 1-channel arbitrary function generator AFG3052C 1 µHz to 50 MHz sine wave, 2-channel arbitrary function generator AFG3101C 1 µHz to 100 MHz sine wave, 1-channel arbitrary function generator AFG3102C 1 µHz to 100 MHz sine wave, 2-channel arbitrary function generator AFG3151C. To plot a sine wave in Excel you can use the instructions in this PDF. The Schmitt trigger is used for wave shaping circuits. Digital data 00H represents -2. Now for a 50Hz sine wave we get a period time 1/50 = 20 milliseconds which is the time required for the sine wave to complete 1 full cycle. One of my preferred methods is to generate a square wave at the desired frequency and then filter out the harmonic components; this approach is described in a sound synthesizer article that I wrote a couple years ago. This article demonstrates how to generate a quasi-infinite number of sounds using math formulas. 0 scale these sine values to match the duty cycle values needed for PWM to a range of 0. ADS-SDA-86-STA kit 2. For example, to set the frequency of the signal: 1.
