1. Digital Signal Processing
Scientech DSP Lab 2.0
Digital Signal Processing is a technique that converts signals from real world sources (usually in analog form) into
digital data that can then be analyzed. Analysis is performed in digital form because once a signal has been
reducedtonumbers;itscomponentscanbeisolated,analyzedandrearrangedmoreeasilythaninanalogform.
Digital Signal Processing (DSP) applications are becoming more prevalent in everyday use. Because of this
widespread usage and advances in computer technology, the DSP algorithms themselves are being subjected to
more demanding specifications. There is a constant need for designing systems with lower power, higher speed
andlessspaceandtoachievethiswearedevelopingnewalgorithms,techniques.
Scientech Technologies DSP Lab 2.0 is an integrated solution for establishing DSP based Embedded System Lab,
based on TI 6000 platform. The lab is designed to learn about the signal processing in Digital Domain. DSP Lab is
equipped with complete set of Hardware and Software to perform DSP experiments. Real -Time DSP Lab 2.0 is
complete solution to understand the real-time DSP systems principles and Real-world applications using, C and
various assembly programs based on TI's TMS320C6713 Processor. Here we designed Real-Time Signal
Processing. Audio Signal Processing & applications oriented windows. In Real- Time signal processing the outputs
are controlled by external inputs as well as virtual inputs. It is advantageous in many areas of DSP like
Instrumentation & telecommunication etc. Audio signal processing is the processing to represent an auditory
signals or sound. The audio effects can be heard by Audio player, which is included withing the software. Single-
Channel, Double-Channel of Multi-Channel windows give the concept of single channel RTDX & multichannel
RTDX.ThesoftwareisdesignedtointeractwithDSPProcessorandconsiststheoryofDSP,
