IS 3413 Lab: Signal CodingIn this lab, we develop the digital signal code fora basic, notional codec. A certain application needs toquantize analog signals varying between -3.5 volts and +3.5 volts (see figure). The proper sampling frequencyhas been determined, and the sensitivity requires that each sample be within 0.5 volts of any true analogsignal (signal displayed as exampleonly).You must provide a digital (binary} code., using the m i n i m u m numbeof bits necessary, to represent each voltage, in 0.5 volit increments, from -3.5 volts to 3.5 volts.O.QVi.ov10ml«StliifrtlSmi«When the blank lines on the left of the figure are filled in with your digital code, the graphwillbe similar to(but not the same as) graphs in figure 3-20 of the text.To complete the assignment,upload a Word (.docx} oiAdobe (.pdf) file with answers to the 2 questions below, followed by a table or list indicating your digitalcode representation for each voltage level as your submission to this assignment in Blackboard.1.How ma n y diff ere nt voltage Ievels m ust be rep rese nted ?-3.5-(-3.5)= 7 V-Internal size= 0.5 = 7v/0.5v= 14 Intervals-The numbers of voltage levels = 14+1= 15 levels2.How many bits are needed to rep resent at /east this many levels (i.e., if the answer to question 1 is,then you must find,such t h a t i * > AT)?-2Ax = N&-From the previouf step, N=15-2Ax=15-Log2A2Ax= log2A15 = 3.9-X=4 bitsPreview Mode
