Consider a discrete time sinusoidal signal xd$($n$)=$ sin$(2$nf$0/$fs$)(5)$ where f$0=5$ kHz and the sample rate is fs $=30$ kHz$.$ A continuous signal x$($t$)$ is constructed using the zero$-$order$-$hold method x$($t$)$ xd$($n$),$ n$$t $$ t $<($n$+1)$t$.(6)$ Since the reconstruction is not ideal x$($t$)$ will also contain sinusoidal components with frequencies higher than the fundamental component at $5$ kHz$.$ Determine $$ the magnitude of the fundamental component in the reconstructed signal. $$ the frequencies and magnitudes of the $3$ first sinusoidal compo nents closest $($w$.$r$.$t$.$ frequency$)$ to the fundamental component in the reconstructed signal.
