This chapter extends the Fourier series representation of discrete time periodic functions to aperiodic functions. We investigate the power of the discrete time Fourier transform in manipulating the ...

The Fourier transform data communication system is a realization of frequency-division multiplexing (FDM) in which discrete Fourier transforms are computed as part of the modulation and demodulation ...

The Fast Fourier Transform (FFT) is a fundamental building block used in DSP systems, with applications ranging from OFDM based Digital MODEMs, to Ultrasound, RADAR and CT Image reconstruction ...

FTIR-7600 is a single-beam Fourier-transform infrared spectrometer with fast scan speed and high accuracy. This instrument is operated by a PC with user friendly software and a comprehensive manual.

The Discrete Wavelet Transform (DWT) has gained the reputation of being a ... FDWT can be performed on a signal using different types of filters such as db9, db7, db4 or Haar. The Forward transform ...

ABSTRACT: Accurate histological classification of lung cancer in CT images is essential for diagnosis and treatment planning. In this study, we propose a vision transformer (ViT) model with two-stage ...
