B) Derive the logic expressions for the incrementor and 7-sgement decoder. Since software can perform gate-level optimization, you don’t need to perform simplification. (c) Derive the VHDL code. The basic "skeleton" is library ieee; use ieee. std_logic_1164.all; -- the g, f, ..., a bars of 7-segment LED are mapped to -- hex(6), ..., hex(0) entity inc_7seg_v1 is port ( a: in std_logic_vector(3 downto 0); hex0, hex1: out std_logic_vector(6 downto 0) ); end inc_7seg_v1; -- only and, or, not operators can be used architecture arch of inc_7seg_v1 is signal s: std_logic_vector(3 downto 0); begin -- incrementor (in terms of a(3), a(2), a(1), a(0)) -- S = A + 1; s(3) <= ... ; s(2) <= ... ; ... s(0) <= ... ; -- 1st 7-sgement decoder (in terms of a(3), a(2), a(1), a(0)) hex0(6) <= ... ; ... hex0(0) <= ... ; -- 2nd 7-sgement decoder (in terms of s(3), s(2), s(1), s(0)) hex1(6) <= ... ;

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
