   2. Deduce linearity, time invariance, and causality from a system input/output equation 1

   3. Draw block diagrams from input/output equation

   4. Calculate and plot impulse system and obtain the transfer function from differential equation/difference equation, block diagrams, system functions

3. Understand CT/DT Fourier transform of a signal

   1. Calculate and plot Fourier and inverse Fourier transform
