Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

Frequency estimation is a critical aspect of modern signal processing, underpinning advances in communications, radar, biomedical imaging and many other fields. At its core, this discipline seeks to ...

When designing space electronics, particularly during the early prototyping stage or if qualification or flight hardware doesn’t function as intended, the humble oscilloscope is often used to verify ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...

Using wideband technology high frequency communications can offer commensurate or increased data throughput over satellite communications in normal or satellite-denied environments to augment command ...

How analog signal engineering is performed, in broad strokes. What are the component-selection considerations for new designs? What are VFAs and how are they used? Analog signal engineers specialize ...

Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, ...

Radar (acronym for Radio Detection and Ranging) uses radio waves to detect objects in the environment. It allows determining the distance (known as range), angular position (bearing), and velocity.
