When you tune in to the radio, the announcer says, “Welcome to 100.1 FM Gold” or “You are listening to Akashvani at 783 AM”. The terms ‘AM’ and ‘FM’ refer to forms of signal modulation — a method at ...

Cochlear implants (CIs) provide important speech cues to deaf patients, but they fail to support the discrimination of temporal sound features with submillisecond precision. Although CIs rapidly and ...

Abstract: This research is devoted to developing the pulse position modulation (PPM) modem, which utilizes an extremely small 40 ps position width to achieve a theoretical bitrate above 149 Mbps. In ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Cortical excitation/inhibition dynamics have been suggested as a key mechanism occurring after stroke. Their supportive or maladaptive role in the course of recovery is still not completely understood ...

Abstract: Pulse Code Modulation(PCM) and Delta Modulation(DM) are important techniques in data conversion and transmission, which have significant impact on the quality of digital signal transmission.
