Periodicity of sum of sinusoids
WebFeb 19, 2024 · 51K views 4 years ago UNITED STATES We know sin (x) is periodic and sin (πx) is also periodic. How about the sin (x)+sin (πx)? Note: The "least common multiple" method helps to find "a" … WebSecond, if sinusoid is the input to a linear system, the output is also a sinusoid. Why are we interested in sinusoids ? • Lastly, through Fourier analysis, any practical periodic signal can be represented by a sum of sinusoids. Therefore, sinusoids play an important role in the analysis of periodic signals.
