This article has analyzed seven signal range capabilities, respectively is the sine signal, the white noise signal, the frequency-modulated signal, the binary system pseudo-random sequence, sweeps the frequency signal, the square-wave signal, two times sweeps the frequency signal.[translate] ...
When a waveform can be represented as the superpositionof a series of sine waves, the amplitude of each sine wavecan be shown by so called frequency spectrum.经振幅调制的波的包络线与调制波形相同。The envelope of the amplitude-modulated wave is identicalto the corresponding modulation waveform....
Besides, in recent years, the boundary value problems of different order differential equations have emerged as an important area of research, since these problems have applications in various disciplines of science and engineering such as control theory, signal and image processing, polymer rheology, ...

In the above ADA4522 block diagram, the i/p signal can be simply modulated to the chopping frequency at the CHOPINstage. The i/p signal at the CHOPOUTstage is synchronously demodulated back to its initial frequency & at the same time, the flicker noise and offset of the amplifier i/p ...

Mathieu equation is a 2nd order differential equation with a periodically modulated coefficient relevant to the squared natural frequency. It describes the parametric excitation of oscillation, 2D vibration in elliptic coordinates, wave propagation in periodically varying medium, etc. Depending on the param...
A high-frequency wave signal is caused by nonradial gas flows in the outer neutron star layers, which are stirred by anisotropic accretion from the SASI and convective regions. The gravitational-wave power then peaks at about 300-800 Hz with distinctively higher spectral frequencies originating ...
The CME is particularly suitable for semiconductor lasers, including quantum dots and especially quantum-cascade lasers with potentially disruptive applications for the generation of frequency combs in the mid infrared region of the electromagnetic spectrum. From a general perspective we expect that the ...
We start with the derivation in the TFD where the quantities of interest are the demodulation and the temporal phase shift between the injected specific intensity and the measured signal. The specific intensity caused by a sinusoidally modulated pencil beam Iincðr, ^s tÞ~dðrÞdð^...
