Mechanical antennas represent a disruptive approach to low-frequency communication by exploiting the mechanical oscillation of electric charges or magnetic dipoles to generate electromagnetic ...

When you tap on your phone screen to check something on the internet, you make use of wireless communications technology. With the advent of 5G networks, this technology has made our lives easier than ...

How does the new HackRF Pro perform in practical tests? We compare it with its predecessor, the HackRF One, and analyze improvements in RF characteristics.

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

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 circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
