Here's how to evaluate and adjust double-tuned circuits for maximum performance. Comment on the relative merits of the two filter designs.Home - Techniek - Electronica - Radiotechniek - Radio amateur bladen - QST - The double-tuned Circuit: An experimenter's tutorialДЄlthough the double-tuned circuit is popular with Amateur Radio experimenters, its response can sometimes be misleading. The transition bandwidths should be given in Hz. An approximate' figure will be sufficient. This can be taken to be the difference between the point where the magnitude response is -3 dB, and the peak of the first ripple in the stop band. There is no need to plot the phase response as it doesn't give us much more information than we already have - can you say why this is the case? From the graphs, estimate the actual transition bandwidth. Also, design a FIR filter of length 51 using the Window Method (use the default Hamming window) and plot its magnitude response on the same graph as the FIR filter of length 51 obtained using the Parks-McClellan method (the magnitude responses should be plotted on a decibel scale). Orders investigated in your Report - only include the frequency response for the filter of order 51. In the interests of brevity, you are not expected to include plots of the frequency response for all filter Experiment with the filter length (order) by designing filters of length ranging from 21 to 51 coefficients in increments of 5 (this is most readily done using a for loop). Note that specifying a filter order of N with the firpm or remez function will result in a filter of length N+1. A digital lowpass filter with the following specification is to be designed: Sampling frequency 8 kHz Cutoff frequency 2 kHz Transition bandwidth 300 Hz Stopband gain 0 (desired) Design an FIR filter to meet the above specification, using the Parks-McClellan optimization technique (Matlab function firpm or remez, if using an earlier version of Matlab).
