Kaz,Thanks again for turning me on to Octave. I re-worked my program in Octave using the fft function an compared it to the Sa function and, guess what, the fft...
Thanks Kaz,I think I see where you are going with the Octave stuff. I will play with it. It sure gets a lot done in a few lines of code! Octave looks like a great...
Sorry about the confusion. Assume that the input signal is a 1 volt rms sinewave swept between two frequencies with the analysis frequency of the Goertzel in the...
I ran a simulation at a couple of frequency resolutions to check. Here are the results..The formula for the 3 dB bandwidth gives 79.6 Hz and the measured bandwidth...
I did a rough simulation of this earlier but with a discrete frequency resolution. I'll give it another go with a swept sine. Thanks!
An interesting project indeed. If I understand your situation correctly you have three mutually orthogonal coils located within a relatively small volume. Each of...
I think that the half power point (3 dB) and the half amplitude point (6 db) are respectively the solution of 1/sqrt(2) = sinx/x and 1/2 = sinx/x is that not...
