The auto-balancing bridge method is an impedance measurement with higher accuracy than other traditional methods. balance control algorithm within the a crucial component. Its performance in maintaining symmetry between current flowing through test element and known reference resistor determines accuracy. However, using imaginary of practical diminishes convergence bridge. In this paper, feedforward decoupling module first constructed to compensate for part decouple into two independent...
Abstract The frequency of a weak signal is used for fault diagnosis and target identification in various fields. By introducing particle swarm optimization (PSO) spectral entropy (SE), an automated estimation method based on the Duffing oscillator proposed. proposed uses differential structure to enhance timing difference between chaotic large-scale periodic states, which quantitatively distinguished by SE. Then, internal driving force adaptively adjusted PSO allow SE reach minimum value...
In the high-resolution analog circuit, performance of chips is an important part. The needs to be determined by testing. According test requirements, stimulus signal with better quality and necessary. main research direction how generate high-speed when there no suitable digital-to-analog converter (DAC) chip available. this paper, we take analog-to-digital (ADC) as example; article uses DAC multiplexers signals that can used for testing ADC based on principle time-alternating sampling. This...
Random demodulation based compressive sampling technique is a novel approach that it can break through the Shannon theorem for sparse signal capturing.A major challenge in random system sequence generation.In this paper, we introduce an to generate high-speed meets incoherence of sampling.The proposed employs field programmable gate array (FPGA).First, parallel stored memory FPGA, and read out byte by using low speed clock.Second, low-speed converted bit circuitry.This program dynamically...
Massive multi-user multiple-input multiple-output (MU-MIMO) systems enable high spatial resolution, spectral efficiency, and improved link reliability compared to traditional MIMO due the large number of antenna elements deployed at base station (BS). Nevertheless, conventional massive MU-MIMO BS transceiver designs rely on centralized linear precoding algorithms, which entail interconnect data rates a prohibitive complexity baseband processing unit. In this paper, we consider an system,...
For most high‐precision power analyzers, the measurement accuracy may be affected due to nonlinear relationship between input and output signal. Therefore, calibration before is important ensure accuracy. However, traditional methods usually have complicated structures, cumbersome process, difficult selection of points, which not suitable for situations with many points. To solve these issues, a method based on sinusoidal excitation DFT transformation proposed in this paper. By obtaining...
