3. Familiarity with the frequency response of FIR and IIR filters.

4. Familiarity with the z-transform analysis of FIR filters.

5. Mastery of combinational logic design by Karnaugh map of 4- to 5-variable functions.

6. Familiarity with digital logic implementation technology and CAD tools.

7. Mastery of number representation in binary, octal and hexadecimal, two’s complement addition,

binary multiplication, and BCD addition.

8. Introduction to multiplexers, codecs and code converters.

9. Introduction to SR, JK and T flip flops; familiarity with D flip flops.

10. Familiarity with synchronous sequential logic design using D flip flops.

11. Familiarity with asynchronous sequential logic design, including races and hazards.

12. Familiarity with Verilog Hardware Description Language.

 

Sample questions

1.  Consider two sinusoids,  x1(t) = 5 cos(2π(100)t + π/3) and x2(t) = 4 cos(2π(100)t + π/4)

        a.  Write x1(t) in phasor form

        b.  What is the frequency in Hz for x2(t).

        c.  Write an expression for y(t) = x1(t) + x2(t)

        d.  If the sum y(t) were to be converted to a discrete signal y[n] by sampling, what is the minimum sampling rate that will enable the original signal to be reconstructed?

       

2.  Determine the z-transform system function for the FIR filter y[n] = 6x[n]- 6x[n-1] + x[n-2].  

 

3.  From the truth table provided, draw a Karnaugh map to represent the sum of products expression for the output variable, O.

            (An alternate form of this would be to give you a K-map and ask you to create the truth table and or a minimized expression.  I won't ask you to deal with any more than four input variables)
