Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

This manuscript presents valuable findings showing that rapamycin directly activates the cool-sensing ion channel, TRPM8, acting through a different binding site than other small-molecule cooling ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...

Abstract: A method is developed to predict, at every sampling instant, the average value of the system variables in a power converter. To achieve this, a model of the converter is used, incorporating ...

If you’ve ever listened to an MP3, watched a movie on Netflix, or jumped on a Zoom call, you’ve used a DAC. Digital-to-analog converters (or DACs for short) are the unsung heroes of the digital audio ...

In previous parts of this series, we described how, when a wavefront approaches an array of elements, there’s a time delay between elements based on the wavefront angle θ relative to boresight. For a ...

One of the most fundamental questions in molecular biology is how quantitative gene expression is achieved. Traditionally, such regulation is ascribed to sequence-specific transcription factors that ...

Amplitude modulation (AM) is a signal modulation technique that is widely used by radio stations for transmitting their programs. This project proposes a Python GUI-based Amplitude Modulation ...

This file type includes high-resolution graphics and schematics when applicable. Information can be sent from a transmitter to a receiver by means of modulation and demodulation, respectively, whether ...
