A system for generating mixed audio output using a multi-dimensional audio map includes a computer processor and a multi-dimensional crossfader configured to implement a method. A metal base is comprised of a first metal and having first and second opposing surfaces and a least one longitudinally-positioned depression in each of the first and second opposing surfaces for receiving a wire. The aortic occlusion catheter passes through a cannula. The effective edge judging unit determines effective edge pixels. The system receives the transmitted communication signal and samples the received signal at a specified rate, the sample rate being less than the symbol rate, enabling reconstructing the waveform and extracting encoded information at sub sample per symbol rates, thereby reducing the reliance on high speed wideband analog to digital converters for high speed applications.
