Given x ( t ), ﬁnd X ( f ). 15. Given X ( f ) and H ( f ), ﬁnd Y ( f ). 16. Given Y ( f ), ﬁnd y ( t ). 17. Given X ( f ) or Y ( f ), draw amplitude and phase spectra. 18. Given X ( f ) or Y ( f ), ﬁnd energy spectral density and total energy (for energy func-tions) or power spectral density and average power (for power functions). 19. Given governing diﬀerence equation of the FIR ﬁlter, ﬁnd its frequency response H (Ω). 20. Given H (Ω), sketch amplitude and phase spectra of the ﬁlter. Indicate periodicity of H (Ω). 21. Given a sinusoidal signal x [ n ] and H (Ω), compute output y [ n ]. 22. Explain relationships between FT, DTFT, DFT, and FFT. 23.
