1. (TCO 3) For a system to be linear it must exhibit which characteristic(s)?

2. (TCO 3) A digital function is written as x[n] = δ[n] – 0.5δ[n – 2]. What is the equation if x[n] is delayed for two samples?

3. (TCO 4) Given a sampling frequency = 1.0 kHz, what is the equivalent digital frequency of an input analog frequency = 200 Hz?

4. (TCOs 3, 4) Given a digital signal is defined by the equation x[n] = 0.5u[n] – 1.5u[n-2], write the equation that describes the input x[n-2].

5. (TCO 4) For a windowed, impulse response low pass FIR filter design, given a transition width of 400 Hz and a pass band edge frequency of 5.0 kHz, what is the desired pass band frequency?
