Combining analog preprocessing with FPGA parallel signal analysis, this paper implements a device for time domain and frequency domain measurement of periodic signals. The system consists of amplifying circuits, a 7 order Butterworth low pass filter, a 14 bit ADC chip Zynq 7020 and a serial port screen, and adopts anal...
Aiming at the problem that the complex electromagnetic environment leads to the decline of electrical parameter detection accuracy and the lag of transient response under the background of new power system, a highly robust signal processing technology scheme is studied. Firstly, a mathematical model of mixed interferen...

This paper presents a multi-stage waveform generator based on second-generation Voltage Conveyors (VCIIs). The proposed architecture enables the generation of multiple waveform types, including a sinusoid, a square wave, a triangular wave, and a reconstructed quasi-sinusoidal waveform. The system is designed using casc...

As core components of radio frequency (RF) front-ends, surface acoustic wave (SAW) filters and duplexers rely on the acoustic wave propagation characteristics of piezoelectric materials, and have become particularly important, driven by the dual demands of multi-band compatibility and integration. However, the traditio...

Due to the crosstalk and electromagnetic interference (EMI) in 3-D integrated circuits, signal integrity degradation remains a critical bottleneck. To address the inefficiency of full-wave electromagnetic simulation and optimization design, the high-efficiency optimization design method for quasi-coaxial through-silico...

. Amplitude Modulation (AM) is both a ubiquitous modern communication technology and is used extensively in the low-power Internet of Things (IoT). In real-life settings, noise in a channel, system flaws, and electromagnetic interference are major factor that plagues the quality of communications, and this aspect requi...
