Digital engineers involved in high-speed communications are at home analyzing signals as a function of time, in the "time domain". However, signals can also be analyzed as a function of frequency, in the "frequency domain". As communications scale up to a million bits per second, digi...
To transform frequency-domainiddataobjectf_datato time-domainiddataobjectt_data, use: t_data = ifft(f_data) Convertingiddatadata into the form of anidfrdfrequency response is a type of estimation. If you want to estimate the frequency response using aniddataobject, seeTransforming Between Fre...
Time domain information from resonant Raman excitation profiles: A direct inversion by maximum entropy A direct method for the inversion of resonant Raman excitation profiles to the time domain is proposed. The inversion procedure is implemented within the m... F Remacle,RD Levine - 《Journal of ...
—We study the frequency- and time-domain techniques which have been used to measure shear attenuation in the mantle using long-period body waveforms. In the time-domain technique, waveform modeling is carried out and the attenuation model that best fits the data is chosen. In the frequency-do...

A traditional approach to signal processing has been, for a long time, the frequency domain analysis, in which time or space periodicities can be identified. It is a relatively simple approach which usually carries significant information, suitable both as a first-step approach for further signal ...
