Question

Consider the signal plot below. Answer the following: a. Is g(t) an analog signal? b. Is g(t) a discrete signal? c. Is g(t) an energy signal? d. Is g(t) a deterministic signal? e. Is g(t) periodic? If it is, what is its period and what is its frequency? f. What is the energy of g(t)? g. What is the average power of g(t)? h. What is the RMS value of g(t)? i. What is the suitable size measure for g(t)? Consider the signal g(t) in the figure below. Answer the following: a. Calculate the signal energy. b. Calculate the signal average power within -2 lessthanorequalto t lessthanorequalto 4. c. Sketch g(t) delayed by 1 and amplitude-scaled by a factor of 2. d. Sketch g(t) expanded by a factor of 2 and time-inverted.

Explanation / Answer

a. yes. it is a continuous signal because its defined in continuous time scale

b.it is a continuous signal so not diserete signal

c. the signal is defined -infinity to +infinity so it is not energy signal its a power signal

d. yes it is a determistic because we can mathamatically determine the value of the signal at given time as it is expressed mathamatically

e. the same signal is repeting after 4sec so it is a periodic with time period 4

f. integral of signal square over -infinity to +infinity is infinity
