c) A visual representation of the spectrum allows us quickly and easily to see interrelationships among spectral components of different frequencies. d) Any periodic signal can be synthesized with a sum of harmonically related sinusoids, even when the sum may need an infinite number of terms. This is the mathematical theory of Fourier series. e) LTI is a linear time invariant system which means a system that whose output obeys the superposition principle and it does not change with time.

Please assist with this practice problem 1 c,d,e with details on how to do it. Thank you.

Question 1: Label each of the following as T for true and F or false: a) One of the reasons that cosine waves are so important is that many physical systems generate signals that can be modeled (i.e., represented mathematically) as sine or cosine functions versus time. b) A discrete-time system is a computational process for transforming one sequence, called the input signal, into another sequence called the output signal. c) A visual representation of the spectrum allows us quickly and easily to see interrelationships among spectral components of different frequencies. d) Any periodic signal can be synthesized with a sum of harmonically related sinusoids, even when the sum may need an infinite number of terms. This is the mathematical theory of Fourier series. e) LTI is a linear time invariant system which means a system that whose output obeys the superposition principle and it does not change with time.
