关于数字信号处理的问题
1.A length-4 complex sequence v[n] = x[n] + jy[n] is given by
v[0] = 1+j,v[1]=1-j,v[2]=2,v[3]=-j,
where x[n] and y[n] are,respectively,the real and imaginary parts of v[n].Determine the 4-point FFT of v[n].
2.If it costs 100 μs to accomplish one time complex multiply,while 20 μs for a complex addition.So calculate out the time cost to complete 1024 points DFT.
