Combining cosines with different frequencies
WebIt is not a linear ramp between frequencies w 1 Hz and w 2 Hz. Look at the derivative of the phase of the signal you generated (i.e. the instantaneous frequency, a somewhat squishy term) and note that its rate of change exceeds w 2 Hz by the end of the array that your code snippet generates. – Jan 24, 2024 at 17:29 1 http://msp.ucsd.edu/syllabi/170.13f/course-notes/node2.html
