DFT can also be obtained using matrix multiplication. Let X[r] show the transformed values and x[n] show the original signal. Using the analysis equation: Using matrix multiplication, this operation can be written as x[O X[1 1 e(2m/N) e-K4n/N) x12] [N-1]] e-j(2(N-1)T/N)e-j(4(N-1)m/N) Instead of huilt-in EFT function use matrix multinlication to solve 3th auestion [ 1 e-/(2(N-1)(N-1)T/N)]Le[N-1] DFT is an extension of DTFT in which frequency is discretized to a finite...

5. Quantitative trait loci(QTL) are: The loci that contribute all of the variation in a continuous trait The loci that contribute all of the genetic variation in a continuous trait The loci that contribute the broad-sense heritability in a continuous trait The loci that contribute the narrow-sense heritability in a continuous trait 6.
