A device for converting frequency-domain data to time-domain data may be provided. The device may include one or more processors. The one or more processors may be configured to transform frequency-domain data to a complex conjugate symmetric of the frequency-domain data over an entire range ...
Deals with a study that proposed a frequency to time domain (ftd) conversion algorithm that represents a seemingly optimal form of recursive convolution. Information on the two subcircuits of a digital very large-scale integration circuit model; Formulation of the ftd algorithm; Details of the ftd...
We propose and demonstrate an ultrahigh-speed optical frequency domain reflectometry (OFDR) system based on optical frequency-to-time conversion by pulse time stretching with a linearly chirped fiber Bragg grating (LCFG). This method will be referred to as OFDR based on real-time Fourier transforma...
In the time domain, the absorption current measurement were prefered up to now. Recent methods are based on the recovery voltage measurements. In this paper a new method of the recovery data conversion from the time the frequency domain is proposed. The method is based on the analysis of the...

It puts forward a algorithm through Conversion factor proportional to the number of coordinates.So,the Time-Domain and Frequency-Domain digital coordinates overlap.Computer let it easy to filter or extract a certain frequency in this process.The simulation shows that the method of signal processing ...
In this new regime, which we will refer to as spectral Fraunhofer regime, the input pulse amplitude is mapped from the time domain into the frequency domain ( time-to-frequency conversion). Here we derive the conditions for achieving time-to-frequency conversion using a single time lens as ...

A different approach consists of using a linear time-domain model based on the Cummins equation which will be referred to as a hybrid frequency–time domain model throughout this paper. The resulting linear model is a vector integro-differential equation which involves convolution terms. Nonlinear ...
each of which was mapped onto many frequency subcarriers with a given modulation format, e.g., QPSK or 16-QAM. These data subcarriers, together with a few pilot subcarriers, are then transferred to the time domain by inverse fast Fourier transform (IFFT). To form a complete OFDM symbol,...
