Web9 apr. 2024 · An essential precondition for the effective use of low-frequency spread-spectrum acoustic signals is their synchronous acquisition. Due to the low bit rate that low-frequency spread-spectrum signals have, the length of the spreading spectrum code and the number of intra-chip carriers need to be precisely designed to balance the acquisition … WebAn impulse response function h (t) has the following formula: inj (t) * h (t) = AIF (t). We know that the graphs of inj (t) and AIF (t) are as followed. I wrote the following code to do the deconvolution but h (t) in the output graph is zero. I realized that the h returns from ifft is NaN but I don't know how to correct the code. qualität eton hemden https://modhangroup.com
