WebChirp. Like noise, it is sometimes useful to play a chirp signal against a receiver. One of the gnuradio tutorials does this in a clean way using a probe. The probe follows a triangle wave level and modifies a sine wave's frequency with that value. As a learning exercise, I wanted to incorporate custom code in gnuradio. philly discount ticketsWebIf the demodulation window is perfectly aligned with the signal, then the peak of the up-chirp and peak of the down-chirp appear at the same frequency, regardless of the CFO, as shown in Figure 5.
