網頁In Matlab you can use the function resample (), but you need to find the resampling parameters P and Q from I. Also, I=1+v/c for signal expansion and I=1-v/c for signal compression. v=speed of movement in m/s and c=speed of wave propagation in the medium. For instance sound underwater c=1500 m/s. In Matlab, you can find P and Q as … 網頁matlab Stepped Chirp Waveform I am trying to plot a stepped FM pulse waveform with a LFM chirp added on each step. I have used the equation below in Matlab, and want to combine the two. 網頁At least one of a center frequency, an amplitude, a starting phase, and a bandwidth of the waveform components are adjusted to generate the single stepped-chirp transmit pulse. A relative phase, a switch time, and a time delay between the waveform components are also adjusted for maximal enhancement of bubble nonlinear response. how many gods are there in the bible
