This paper investigates the accuracy of a recently proposed sine-wave frequency estimator based on the interpolation of Discrete-Time Fourier Transform (DTFT) spectrum samples located one frequency bin apart.
The desired signal is a BPSK signal with 4 samples per symbol, located at frequency 0.2.
The interference is a pure sinusoid located at frequency 0.7 and with SNR = 10dB.
As seen from Figures 3 and 4, there are three prominent peaks located at frequency equal to 0, 2π/3, and 4π/3.
Subsequent peaks are located at frequency multiples of the mean respiratory rate.
These components may be located at frequencies with large differences or at very close frequencies.
Finally, a strategy is demonstrated that allows for the measurement of the 14N quadrupolar parameters for any nitrogen moiety whose quadrupolar coupling constant falls within the range 0.8≤|CQ|≤1.5 MHz, by acquiring only two 14N NMR sub-spectra at strategically located transmitter frequencies; these results are compared to full powder patterns which are acquired using frequency-stepped methods.
Raman bands observed in SERS spectra were very broad and located at frequencies lower than the NR bands.
FFT domain processing sharpens the notch provided by the time domain filter, but it also reduces the attenuation at the symmetrically located stopband frequencies.
From Figure 3e, it is observed that the G-band's peaks are located at frequencies 1621 and 1610 cm-1, for SWNT1 and SWNT2, respectively.
