Keep in mind, we are after all, taking about windows. An operating system that IS NOT real time operating system. (You think it is, try move a continuous stream of a few 6+ MBytes/Sec data to it!)
Well, the Perseus SDR, when set to its maximum sampling rate after the DDC, sends the I and Q continuous streams (24 bit/sample each), to the PC at a rate of 2 MHz. This means 12 MBytes/sec via a high speed USB2 port. Using one the many available SDR programs, those 12 MBytes/sec are received, FIR and FFT are applied, demodulation algorithms are used, and there are no glitches in the final audio... if even a single sample would be lost, you would ear immediately the artifact.... Windows is not as bad as somebody would depict it... :-) 73 Alberto I2PHD _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
