DESIGN OF NOVEL GENERALIZED LOW PASS FILTER CASCADED WITH PASSBAND NOTCH FOR MRI APPLICATIONS
Get PDFSynthesis and design of a lumped-element low-pass filter cascaded with passband notch are done in this project. The filter synthesis and design are stringently carried out using Maple and done based on exact computations involving mainly the determination of the elements specifications. The design of the filter consisted of utilization of inductors and capacitors with Chebyshev approximation in which the elements values are obtained through insertion loss method and the resulting circuit is simulated via Advanced Digital Systems (ADS). The resulting frequency response of the filter is conforming to the given specifications with a total filter order of less than 15 in order to allow a better selective response and also avoid high power loss, high cost and complication in prototype fabrication later on. The main advantage of the cascaded filter is its better ability to increase the signal to noise ratio in Magnetic Resonance Imaging (MRI) equipment
