AVR223: Digital Filters with AVR
ثبت نشده
چکیده
Applications involving processing of signals from external analog sources/sensors usually require some kind of digital filtering. For extremely high filter performance, Digital Signal Processors (DSP) are usually chosen, but in many cases these are too expensive to use. In these cases, 8and 16-bit Microcontrollers (MCU) come into the picture. They are inexpensive, efficient, and have all the required I/O features and communication modules that DSP seldom have.

متن کاملDesign 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...

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
