Dear all: I got some data,and I converted the data to the frequency domain by taking fast Fourier transform.Also,I calculated the power spectrum at various frequencies. However,I want to know the ratio of the characteristic (single)frequency's power to all frequencies' power.I tried for a long time,but I failed to make it.I deeply hope someone can tell me how to do for it.That's all.Thank you all in advance. xu3djpu4 |
