3. With the aid of a diagram, briefly explain th ing principle of a Successive a) Approximation Analog-to-Digital Converter (ADC) b) An ADC has to be designed to convert voltages in the range from -5 V to +5 V, with a resolution below (better than) 1 mV. What is the minimum number of bits required to meet this design specification? An ADC has to be designed to convert input voltage signals with frequency c) components less than or equal o...

Design and implement a 3-band equaliser using a DSP board or MPLab/CSS. The MATLAB Filter Designer could be used for filter design and graphing subject to the design requirements given below. This is an individual CW 2. Equaliser Primer An n-band equaliser is a device used to correct the frequency response characteristic of a signal processing system. Equalisers can be implemented using digital or analogue filters. The whole bandwidth of the equaliser is divided into n frequency bands, which can...
