The sequence of numbers can represent anything from digitised human speech to stock price data, processed to detect hidden periodicities or pattern

• ### Digital Filters

The new technologies and communications systems are being set up in all areas. It leads to treating data from different sources and for several proposes. But it is necessary to obtain only the information that is required. Digital filters, together with analogue filters, are used for these objectives. The main advantage of the digital filters is that they can be applied at zero cost and with a great flexibility.

• ### Báo cáo " Multiband fiR Filter Design and implementation to recover real- time corrupted input speech using dsk tms320c6711 "

In this paper, the five-band notch filter was designed using MATLAB and implemented by the floating-point digital signal processor TMS320C6711 based on TI's DSP starter kit (DSK) board connected to the parallel port of the PC through the DB25 cable included with the DSK package. The original segment of symphony orchestra corrupted two undesired sinusoids at frequencies of 750Hz and 1750Hz is conduced to input of DSK to produce the corrupted input signal which is saved in the wave file (Corrupthandel.wav) for the digital signal processor. ...

• ### Design of efficient circularly symmetric two-dimensional variable digital FIR filters

Circularly symmetric two-dimensional (2D) finite impulse response (FIR) filters find extensive use in image and medical applications, especially for isotropic filtering. Moreover, the design and implementation of 2D digital filters with variable fractional delay and variable magnitude responses without redesigning the filter has become a crucial topic of interest due to its significance in low-cost applications. Recently the design using fixed word length coefficients has gained importance due to the replacement of multipliers by shifters and adders, which reduces the hardware complexity.

• ### Active Filter Design Techniques

What is a filter? A filter is a device that passes electric signals at certain frequencies or frequency ranges while preventing the passage of others. — Webster. Filter circuits are used in a wide variety of applications. In the field of telecommunication, band-pass filters are used in the audio frequency range (0 kHz to 20 kHz) for modems and speech processing. High-frequency band-pass filters (several hundred MHz) are used for channel selection in telephone central offices.
