[QUOTE="electronic engineer, post: 4989900, member: 43209"] [h2]Homework Statement [/h2] We have the following signal frequencies: f1=18 Hz, f2=510 Hz, f3=1100 Hz when using the sampling frequency fs=1000 Hz. how would these signals be like? my question is if I could use the same formula stated below for all the frequencies f1,f2,f3.. because the second and third ones are above the Nyquist Frequency fc=fs/2=500 Hz so there would be aliasing in this case. and what about the graphs for these samplings? [h2]Homework Equations[/h2] when using another sampling frequency fs=1002 Hz and here also would be the same questions. [h2]The Attempt at a Solution[/h2] [B]I used the formula: [/B] [B]$$ S_{\Delta }(v)= f_{s}\sum_{n=-\infty}^{+\infty}(S(v-n*f_{s})) $$[/B] [B]for the first frequency f1= 18 Hz I had: [/B] [B]$$ S_{\Delta}(18)=1000\sum(S(18-n*1000)) $$[/B] [B]where $$ n=-\infty $$ to $$ +\infty $$[/B] [/QUOTE]
