Therefore, the shift in local maxima of estimated periodogram (PSD) is related to maximum Doppler frequency, which is proportional to the mobile speed ( ν ^ ∝ f ^ d. λ ) in which υ ^ i is estimated speed under i th window and λ is wavelength [4].
But it is also understood that halving the voltage also reduces the processor's maximum operating frequency which in turn leads to performance loss.
The cut-off frequency fT is defined as the frequency at which the current gain becomes unity and indicates the maximum frequency at which signals can be propagated in the transistor.
The distance between the used subcarriers in the pilot subsymbols A is equal to (assuming every subcarrier of every pilot symbol is used), so is the maximum frequency offset which can be estimated.
Figure 4 presents the STFT, MP, MPWD, and AD-PCNN spectrograms and their maximum frequency waveforms, which are superimposed on the spectrograms with the solid curves, of a simulated original, MP-based and PCNN-based noise and speckle reduced Doppler signals with different noise levels (SNR = 0 dB, 5 dB, and 10 dB), respectively.
Although heel-strikes repetitively occur at this rate only after an individual gait cycle, this does provide a maximum frequency at which to measure mechanical stiffness.
The superfast muscles found in the songbird syrinx are pushed to the performance limits of vertebrate skeletal muscle so that their work output is 10 to 20 times lower than regular skeletal muscle [ 36, 49, 84] and a distinct trade-off exists between the work they can generate and the maximum frequency at which they can cyclically actuate objects [ 49, 85, 86].
Large actions, therefore, would result in a large combinatorial logic and reduces the maximum allowable operating frequency which in turn decreases throughput.
The lower frequency range 0 to 1 kHz captures the fundamental frequency which has maximum energy with most speaker-specific information.
For the pair of impulses with the same polarity, the spectrum has spectral maxima at frequencies which are multiples of the inverse delay time between impulses, namely 1, 2, 3,... Hz; whereas for impulses with opposite polarities at these frequencies the spectral minima are formed.
