So, yes, a sound card designed for signals up to ~22kHz should handle SAQ at ~17kHz, but sound cards that can digitize signals above 22kHz are rare. Some "professional" sound cards handle signal frequencies up to ~40kHz, but very, very few handle signal frequencies higher than that. There are also digitizers designed more for instrumentation and data acquisition than audio that may meet your requirements.
Bob and Charles,
you are of course both quite right. The card used for SAQ was the Delta 44 which is a semi-professional card. For higher frequencies I have had quite good results with the E-MU 1212M, which is a professional, mastering grade, sound card, used also in recording studios. http://www.creative.com/emu/products/product.aspx?pid=19169 Not exactly inexpensive, but its 120dB signal-to-noise ratio cannot be overlooked. 73 Alberto I2PHD _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
