design compact. A band pass filter is designed to have a fractional bandwidth of 0.28 at a centre frequency of 2.5 GHz. A 5 pole chebyshev low pass prototype with a pass band ripple of 0.1 db is used. The element values are g0=g6=1.0, g1=g5=1.1468, g2=g4= 1.3712 and g3=1.9750. These low pass element values are used

Bandwidth of lowpass filter? - Signal Processing Stack ... E.g., any digital low pass filter has a cut-off frequency that is fixed with respect to the sampling frequency, but it's not fixed as an absolute frequency! If you leave the filter coefficients unchanged and you change the sampling frequency, also the cut-off frequency will change. Bandwidth of low pass filter - Electrical Engineering ... I know for example that with bandpass filters it's the difference between +-3dB of the cutoff Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
