| Abstract | ||||
| A new approach is described for generation of pseudorandom of wide band which could be considered as white Gaussian noise. This is achived by using nonrecursive digital filter with specified transfer function which compensates the spectrum decay of pseudorondom binary sequence (m-sequnce). The optimized filter parameters (i.e. filter length Np, sampling points M using frequency sample technique) for fluctution ( &) 0.2 dB in the passband of proposed filter Np 61 and M 400, are considered. The results of simulation of desinged filter performance gave NF = 61, band width = 0.25 fc " fc clock frequency and the sequence length L = (2Ale -. 1), for- g. The increasing in band width is indicated and is very satisfactory as compared with the existing data (i.e. band width = 0.05 fc ). | ||||
