If you could make your square wave frequency higher than the desired sine wave then you could digitally generate a sine wave using a sine lookup table. The string is driven by a wave driver, which excites the string in a direction perpendicular to the string. For higher frequencies, you can make a smaller table (that is, maybe 1 entry for each 2 or 3 or more degrees) and get a faster output, at the expense of a less clean sine wave. I am working on a function that will generate a sine wave at a given frequency AND sampling rate. A sine wave frequency shows, how much the medium particles undergo in vibration when a wave is passed through that medium. One of these is that the when the applied ac voltage is a sine wave, as shown in red in the graph to the right, the resulting current is actually shifted in phase by 90° — it is a cosine wave, as shown in blue in the graph. kindly guide me. This article discusses about Sawtooth Wave Generator and its working principle using 555 and OP-AMP, and also about sine, cosine wave and its applications. The general sine wave shape is “amplitude*sin(frequency*(t+delay))”. i+1 = t i + Δt (Equation 1) Note: you need to fix the cell for delta t in Equation 1. Re: sine wave trendline. ) Continued C. Of course, the second half of the equation is a sine wave and the first half is a cosine wave, so you must include a device in the hardware circuit to induce a 90-degree phase shift between the carrier signals used for the I and Q mixers, but this addition is a simpler design issue than the aforementioned direct phase manipulation.
