Ifthen which of the following is the backward design equation for a low pass-to-band pass transformation?
A. ΩS= |B| B. ΩS= |A| C. ΩS= Max{|A|,|B|} D. ΩS= Min{|A|,|B|}
Explanation: If Ωu and Ωl are the upper and lower cutoff pass band frequencies of the desired band pass filter and Ω1 and Ω2 are the lower and upper cutoff stop band frequencies of the desired band pass filter, then the backward design equation is
