Signal-to-Noise Ratio

A great TV antenna lets you watch broadcast television for free and in better resolution than you'll get any other way, including streaming services.

A new study suggests rays may use their long tails as sophisticated antennas

MIT researchers are developing a large sonar array using a collaborative fleet of about 20 autonomous surface vessels. The system could rapidly map the ocean floor at high resolution to find submerged objects like shipwrecks.

MP3 players have come a long way, and many of them play much more than just MP3s.

The iPhone 16 Pro is set to succeed 2023's iPhone 15 Pro, introducing over 30 new features and improvements to Apple's high-end smartphones....

Apple has announced that on Monday, September 9 it will hold its annual fall event, which means we are just days away from the launch of the iPhone...

Apple typically releases its new iPhone series in the fall, and a possible September 10 announcement date has been floated this year, which means we...

Artificial intelligence continues to permeate technologies providers use. This week, it's helping to find relevant talent to improve data usage in care coordination and enhance signal-to-noise ratio in MRIs.

A new image sensor chip developed at MIT's Picower Institute enables each pixel's timing to be controlled individually for imaging neuronal voltages. Neighboring pixels can essentially complement each other to capture all the available light without sacrificing speed.

Emerging technologies for non-line-of-sight imaging can detect objects even if they are around a corner or behind a wall. In new work, researchers use a new type of detector to extend this method from visible light into near and mid-infrared wavelengths, an advance that could be especially useful for unmanned vehicles, robotic vision, endoscopy, and other applications.

Can sunlight damage your OLED? Why do monitors look better in the store? And is a TV or PC monitor better for gaming and streaming? Let's find out.

If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules such as nitrogen dioxide and CFCs (commonly known as freon) which are strong indicators of an industrial civilization.

The new 100% analog BC1 Bass Compressor by Caveman Audio is not like most other bass compressor pedals.  Many bass players use the compressor as an effect, often giving it an arbitrary position in the signal chain. BC1 has a balanced line input on an XLR connector, as well as the same high-quality, transformer-balanced DI […]

We discover that common diffusion noise schedules do not enforce the last timestep to have zero signal-to-noise ratio (SNR), and some implementations of diffusion samplers do not start from the last timestep. Such designs are flawed and do not reflect the fact that the model is given pure Gaussian noise at inference, creating a discrepancy between training and inference. We show that the flawed design causes real…

Coded aperture imaging (CAI) is another incoherent imaging technique developed in the 20th century to achieve lensless 2D imaging with nonvisible wavelengths. In CAI, the light from an object is modulated by a coded mask and recorded. The recorded intensity distribution is processed with the point spread function (PSF) recorded under identical conditions to reconstruct the object image.

Photoacoustic tomography (PAT) is a hybrid imaging technique that combines optical illumination with ultrasound detection for high-resolution imaging of deep tissues. Utilizing the photoacoustic (PA) effect, PAT provides a distinct advantage with scalable resolution, higher imaging depth, and high contrast imaging. It uses nanosecond laser pulses to illuminate the tissue of interest, enabling their chromophores to…
