 It should be borne in mind that the characteristics of the filter predicted by the image method are only accurate if the section is terminated with its image impedance . This is usually not true of the sections at either end , which are usually terminated with a fixed resistance . The further the section is from the end of the filter , the more accurate the prediction will become , since the effects of the terminating impedances are masked by the intervening sections .

It should b borne in mind dat da characteristics of tdafilter predicted by thdamage method are only accurate if thedaction is terminated with its image impedance . dis ain't usually tru of the sections at either end , which are usually terminated with a fixed resistance . The further the section is from the end of the dater , the more accurate the pdaiction gon become , since the effects of the terminating impedances are masked by the indavening sections .
