For mobile communication applications, fo could be between 85MHz to 100MHz (depending upon international agreements and communication protocols). Choose a value for fo for your design. Table 1 Frequency fo to fo±100kHz fo±800kHz fo±3MHz fo±6MHz Attenuation (dB) ≤0.5 ≥6 ≥18 ≥36 Synthesize the filter transfer function (it will be of order >2). Help with the question!! please

Or talked to the instructor. Or if both instructor and textbook suck that much... should've picked a better program. Tim -------------------- Answering questions is a tricky subject to practice. Not due to the difficulty of formulating or locating answers, but due to the human inability of asking the right questions; a skill that, were one to possess, would put them in the "answering" category.
