Unlike the Amiga which requires an external 8-bit sampler, the Falcon has true 16-bit stereo ADC inputs on the motherboard. The 14.2 Hz peak shows up as a bright white vertical line against the blue background noise. Requires 4MB ST-RAM and an RGB or VGA monitor. -- Morag Dubois Opinions expressed are solely my own and not those of University of Tokyo Department of Information Science. ------------------------------------------------------------ From rtakahashi@uni-hamburg.de Tue Aug 22 23:47:51 1995 Path: ashpoly!bigsur!pacrim!krgate!eunha!uni-hamburg!rtakahashi From: rtakahashi@uni-hamburg.de (Rodrigo Takahashi) Newsgroups: comp.sys.m68k Subject: Re: [SPECULATION] Atari Falcon 030 Motorola DSP56001 code for Stardust carrier extraction Message-ID: <1995Aug22.234751.5373@uni-hamburg.de> Date: Tue, 22 Aug 1995 23:47:51 GMT References: <1995Aug20.215151.7459@u-tokyo.ac.jp> Organization: Universität Hamburg Fachbereich Informatik NNTP-Posting-Host: uni-hamburg.de X-Newsreader: TIN [version 1.2 PL2] Lines: 9 In article <1995Aug20.215151.7459@u-tokyo.ac.jp>, mdubois@u-tokyo.ac.jp (Morag Dubois) writes: > Real-time spectral waterfall and DBPSK demodulator for TOS 4.04.
