AN9603: An Introduction to Digital Filters
ثبت نشده
چکیده
Introduction Digital Signal Processing (DSP) affords greater flexibility, higher performance (in terms of attenuation and selectivity), better time and environment stability and lower equipment production costs than traditional analog techniques. Additionally, more and more microprocessor circuitry is being displaced with costeffective DSP techniques and products; an example of this is the emergence of DSP in cellular base stations. Components available today let DSP extend from baseband to intermediate frequencies (IFs). This makes DSP useful for tuning and signal selectivity, and frequency up and down conversion.

Design of IIR Digital Filter using Modified Chaotic Orthogonal Imperialist Competitive Algorithm (RESEARCH NOTE)
There are two types of digital filters including Infinite Impulse Response (IIR) and Finite Impulse Response (FIR). IIR filters attract more attention as they can decrease the filter order significantly compared to FIR filters. Owing to multi-modal error surface, simple powerful optimization techniques should be utilized in designing IIR digital filters to avoid local minimum. Imperialist compe...
