NICHTREKURSIVES HALB-BAND-FILTER |
摘要 |
The invention relates to a non-recursive half-band filter and makes it possible to convert a real input signal into a complex output signal, by modulating its pulse response to the complex carrier of a frequency equal to 1/4 or 3/4 of the sampling frequency, the null phase of this frequency being an integral multiple of pi /2, and also makes it possible to convert a complex input signal into a real output signal, by modulating its pulse frequency to the complex carrier of a frequency equal to the input sampling frequency or half thereof, the null phase of this frequency being an integral multiple of pi /2.
