The amplitude is determined by the Fourier transform of the isolated purse constituting the periodic pulse train. Since the input frequency components are discrete, simulation of the output response requires only the sampled values of the frequency characteristics of the circuit. Since the Fourier ...
Frequency Following Response The frequency-following response (FFR) is a scalp-recorded response that has the same frequency as the tone used to elicit it. From: Fetal and Neonatal Physiology (Fourth Edition), 2011 Set alert About this page ...
The sin(x)/x (sinc) function is well known in digital signal processing. For DACs, the input is an impulse and the output is a constant-voltage pulse with update period of 1/fS(the impulse response), whose amplitude changes abruptly in response to the next impulse at the input....

aFigure 1 represents a simulated impulse train, each impulse is modulated by a single harmonic frequency with exponential decay.The signal can be considered as a model of a rolling element bearing defect signature [3, 4]. The defect frequency is taken equal to 100 Hz and the natural ...
"""Generates impulse response implementation of equalization filter.""" # Interpolate to even sample interval fr = self.__class__(name='fr_data', frequency=self.frequency, raw=self.equalization) # Save gain at lowest available frequency f_min = np.max([fr.frequency[0], f_res]) interpolat...
The period and its distance between the successive peaks are related to the fundamental frequency component of the original signal. The speech signal is perceived as the process of convolution of the excitation source and impulse response of vocal tract filter [36, 37]. The objective of cepstrum...
According to the number of modes,K, the average Pearson correlation coefficientρ¯is calculated as follows: ρ¯=1K−1∑i=1K−1ρ(IMFi,IMFi+1). (6) 2.2A New BALW Different types of shocks had different shock response performances, mainly due to the different mechanisms and materials...
The test setup consisted of a function generator (MEGATEK, MFG-2205P), a broadband longitudinal piezoelectric transducer with a center frequency of 100 kHz, a receiver, an amplifier, and a digital oscilloscope (OWON, TDS-7104) to record the longitudinal wave response. In the testing, the funct...
Also, the fact that not all spectral components fade together can be exploited as a form of frequency diversity. Since in a wireless system terminals are allowed to move, the channel impulse response changes in time in general. Even in the case in which terminals do not move, the ...
