![]() What is the lowest sampling rate allowable in this system given the above constraints and giving that the anti-aliasing and reconstruction filters are not quite ideal: they have 6 MHz transition bands?" The maximum frequency that needs to be preserved in the reconstructed analog signal is 90 MHz. Assume that ideal sampling is used as well as ideal anti-aliasing and reconstruction filters. The system uses an analog-to-digital converter (ADC) to digitize the analog input, a digital signal processing chip (DSP) to filter the digitized signal, and a digital-to-analog (DAC) converter to convert the signal back to analog. ![]() " You have been asked to design a real-time digital filtering system that eliminates a band of frequencies between 20 and 30 MHz but preserves everything else.
