IIR & FIR 1/23/2012ANALOG AND DIGITAL FILTERS: ANALOG AND DIGITAL FILTERS ANALOG FILTERS APPLICATIONS: SEPERATION OF AUDIO SIGNAL FROM THE SIGNAL RECEIVED. THE SELECTION OF CHOSEN RADIO STATION AND REJECTION OF OTHERS IN THE TUNER DIGITAL FILTER APPLICATIONS: A DIGITAL FILTER IS A SYSTEM THAT PERFORM OPERATIONS ON SAMPLED, DTS TO ENHANCE CERTAIN ASPECTS. 1/23/2012DIGITAL FILTERS: DIGITAL FILTERS CLASSIFICATIONS: IIR (INFINITE IMPULSE RESPONSE) FIR (FINITE IMPULSE RESPONSE) THESE CAN BE AGAIN CLASSIFIED AS HIGH PASS, LOW PASS, BAND STOP & BAND PASS FILTERS. 1/23/2012Fir filter: Fir filter 1/23/2012FIR OVER IIR: FIR OVER IIR ADVANTAGES OF FIR OVER IIR IIR filters are difficult to control and have no particular phase, whereas FIR filters make a linear phase always possible. IIR can be unstable, whereas FIR is always stable. IIR, when compared to FIR, can have limited cycles, but FIR has no limited cycles. They are suited to multi-rate applications. 1/23/2012FIR BAND PASS: FIR BAND PASS BAND PASS FILTER A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. Optical band-pass filters are of common usage. 1/23/2012Interpolation and decimation SAMPLING: Interpolation and decimation SAMPLING 1/23/2012INTERPOLATION AND DECIMATION QUANTIZATION: INTERPOLATION AND DECIMATION QUANTIZATION 1/23/2012INTERPOLATION AND DECIMATION INTERPOLATION: INTERPOLATION AND DECIMATION INTERPOLATION 1/23/2012INTERPOLATION AND DECIMATION DECIMATION: INTERPOLATION AND DECIMATION DECIMATION 1/23/2012ADANTAGES OF INTERPOLATED AND DECIMATED SIGNALS: ADANTAGES OF INTERPOLATED AND DECIMATED SIGNALS Telecommunications Image Processing Medicine 1/23/2012 Speech Processing MilitaryPROJECT: PROJECT NOW THE EXECUTION OF A FINITE IMPULSE RESPONSE INTERPOLATED AND DECIMATED SIGNAL USING KAISER WINDOW (WITH DIFFERENT CO EFFICIENTS) IS DONE IN VISUAL DSP SOFT WARE. 1/23/2012PROJECT: PROJECT DSP PROCESSORS A Digital Signal Processor (DSP) is a specialized microprocessor with an architecture optimized for the fast operational needs of digital signal processing. 1/23/2012PROJECT: PROJECT VARIOUS VENDORS IN DSP ANALOG DEVICES TEXAS INSTRUMENTS SEOUL SEMI CONDUCTORS FREE SCALE MICRO CHIP etc… 1/23/2012PROJECT: PROJECT ANALOG DEVICES PROCESSORS BLACK FINN SHARC TIGER SHARC 1/23/2012PROJECT: PROJECT SHARC PROCESSORS The name “SHARC” refers to a family of high-performance, 32-bit.
