Results are given in Table 1. a monofrequency excitation which consisted in a pulsed-wave signal of a pure sine wave at frequency f0 = 550 kHz, a bifrequency excitation which consisted in a pulsed-wave signal made of the sum of two sine waves of slightly different frequencies, f1 = 535 kHz and f2 = 565 kHz, and of the same pressure amplitude.
Two types of pulsed-wave excitation were used, according to [ 25]: a monofrequency excitation which consisted in a pulsed-wave signal of a pure sine wave at frequency f 0 = 550 kHz, a bifrequency excitation which consisted in a pulsed-wave signal made of the sum of two sine waves of slightly different frequencies, f 1 = 535 kHz and f 2 = 565 kHz, and of the same pressure amplitude.
The NEE is comprised of signals made up of photosynthetic uptake, gross primary production (GPP), as well as autotrophic and heterotrophic respiration, called the ecosystem respiration (ER).
It is clear that the CTMF of sine or cosine signals is made of Dirac's deltas at cycle frequencies,, and.
These special proteins contain a specialized retention signal made up of a specific sequence of amino acids that enables them to be retained by the organelle.
Note that the transmitted signal is made of the time domain OFDM symbol together with the cyclic prefix.
For instance, in downlink CDMA systems, the emitted signal is made of multiuser chip symbols shaped by the chip waveform at the transmitter output.
From a communication point of view, platelets act as mobile transmitters, endothelial cells are fixed receivers, sticky to the vessel walls, and the transmitted signal is made of bursts of molecules emitted by platelets.
The auditory signal was made of one or two 7 ms beeps with a frequency of 3500 Hz.
Clearly, having such frequent epidemic alert signals makes the usefulness of such techniques in this particular area of the western Kenyan highlands questionable.
