FIELD: electric engineering, in particular, automatic equipment of power supply systems. SUBSTANCE: method involves generation of additional signal by means of phase shift of source signal in arbitrary direction without alternation of its amplitude, generation of first and second additional signals as ...
Firstly, we'll let Omni's phase shift calculator do the talking. At the top of our tool, we need to choose the function that appears in our formula. In our case, we choose "sine" under "The trigonometric function in f." That'll trigger a symbolic representation of such a phase ...
19.3.3 Phase shift keying If phase modulation is used to transmit a digital signal, this is known as phase shift keying (PSK). If the signal is binary, the phase of the carrier is shifted between two positions which are 180° apart. This is sometimes known as phase reversal keying (PRK...

Apply phase-shift beamforming to the signal received by a 5-element ULA. The beamforming direction is 45° azimuth and 0° elevation. Assume the array operates at 300 MHz. Specify the beamforming direction using an input port. Simulate a sinewave signal arriving at the array. ...
when the sum of phase shift of longitudinal vibration and torsional vibration is less than 180°, the vibration direction is clockwise, and when it is greater than 180°, the vibration direction is counterclockwise, and the phase difference will directly affect the long axis direction of the tool...
Phase-Shift Keying is a digital modulation scheme that conveys data by changing, or modulating, the phase of a reference signal (the carrier wave). In the code, the carrier is a sine wave and following the block diagram for the transmitter and receiver components, the output is obtained.收藏...

neural network, especially when the spatial characteristics differences of the phase between the training and testing datasets are relatively large89. Since the phase-shift between the generated holograms is equal, Yan et al.91proposed to generate noise-free phase-shifting holograms using a simple ...
In this paper, phase shift frequency variable sine signal generator with DDS as its core was designed based on Field Programmable Gate Array(FPGA) and hardware description language(VHDL). The experimental and simulation results show that the system has stable output frequency, high frequency accuracy...
