Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
The proliferation of wireless devices and services has led to a critical issue of spectrum scarcity. Despite this, a significant portion of the licensed radio spectrum remains underutilized for large ...
Active metasurfaces enable dynamic manipulation of the scattered electromagnetic wavefront by spatially varying the phase and amplitude across arrays of subwavelength scatterers, imparting momentum to ...
Frequency spread spectrum (FSS) is a technique that’s been widely used in power-conversion designs to reduce electromagnetic-interference (EMI) noise. But optimizing EMI without compromising on other ...
