The sind operation is element-wise when X is nonscalar. Sine of angle, returned as a real-valued or complex-valued scalar, vector, matrix, multidimensional array, table, or timetable of the same size as X. This function fully supports tall arrays.

Help Center Help Center. This example shows how to find the root mean square RMS value of a sine wave, a square wave, and a rectangular pulse train using rms. The waveforms in this example are discrete-time versions of their continuous-time counterparts. The length of the signal is 16 samples, which equals two periods of the sine wave. Create a periodic square wave with a period of 0. The square wave values oscillate between - 2 and 2. Create a rectangular pulse train sampled at 1 kHz with the following parameters: the pulse is on, or equal to 1, for 0. This means the pulse period is 0.

Could you explain how the process you set out will solve the original question posted in ? The tone at 1 kHz is filtered out and attenuated. Show older comments. While running the simulation, the spectrum analyzer shows that frequencies above Hz in the source signal are attenuated. Edited: DGM on 16 Mar Sir please solve this. AluminiumMan on 15 Mar Method used to generate sinusoids, specified as one of the following: 'Trigonometric function' —— The object computes the sinusoid by sampling the continuous-time function. Search Answers Clear Filters. Based on your location, we recommend that you select:. Save Article Save. The Frequency specification parameter lets you choose the method of specifying the frequency of the sine wave: If you select Frequency SI , specify the frequency in Hz or in units directly convertible to Hz such as kHz , MHz , and GHz.

Tags sine waves. The first example of the plot function doc exactly shows how to plot a sine wave. Sign in to answer this question. Create a bandpass filter design specifications object using fdesign. Vote 1. For example, to release system resources of a System object named obj , use this syntax: release obj. Do you want to open this example with your edits? Based on your location, we recommend that you select:. Hi AluminiumMan. By constraining trigonometric evaluations to the first cycle of each sinusoid, the algorithm avoids the imprecision of computing the sine of very large numbers. Frame-based processing is advantageous for many signal processing applications because you can process multiple samples at once.
