Some may say the 11th harmonic is sufficient. WebSay I have a sum of two sinusoids like so: A c o s ( x t + ϕ) + B c o s ( y t + δ) How would I find the period? I know that for just one sinusoid the period would be: A c o s ( x t + ϕ) T = 2 π / x It can't be as simple as just adding the two periods. How can I tell if they're not periodic? periodic-functions Share Cite Follow gesetz coronabonus 2022

WebAnswer (1 of 3): I assume that by “sinusoid” you mean a function of the form y = a sin (bx + c). Note that a function of the form y = a cos (bx + c) is also a sinusoid since cos x = sin (x + π/2) for all values of x. I don’t think the other answer really answers your question.

WebAbstract—In this letter, an improved sum-of-sinusoids simulation model is proposed for Rayleigh fading channels. The new model employs random initial phase, and conditional random Doppler frequency for all individual sinusoids. The second-order statistics of the new simulator match the desired ones exactly even if the number of sinusoids is a ...
