1. The problem statement, all variables and given/known data Create a VI that will: simulate two sine waves of different frequencies (run it for 20 and 12 0 Hz). Add the sine waves and plot the sum. Then use a filter to remove signals above 50 Hz, and plot the filtered res 2. Relevant equations 3. The attempt at a solution I have attached an image of what my program currently. I've managed to plot the 20Hz and 120Hz sine waves in a waveform graph, but I'm having difficulty with filtering out the signals with a frequency above 50Hz. Any suggestions and advice would be appreciated. Thank you. EDIT: I tried going into properties with the filter and setting the cutoff frequency at 50Hz, but the error message still shows. EDIT 2: Just realized that I how I wired the signal to the filtered signal didn't make sense. Have now fixed that, but the filtered signal doesn't look all that different from the unfiltered signal.
