                    ECE 601 : Linear Systems

Description: Analysis of dynamic linear systems using time and frequency
domain representations followed by state space models. Linkages among
these analytic techniques are developed and provide the systems background
needed for subsequent studies in communications and control.

Ground Rules

       (1) Homework to be assigned every week and due the following week;
          Solutions will be distributed at that time.
       (2) Two equally-weighted exams : mid-term and final.
       (3) Semester grade .based on exam grades; borderline cases decided on
           basis of submitted HW

Honor Code
      The NJIT honor code will be upheld and any violations will be brought
      to the immediate attention of the Dean of Students.
