Designed to maximally extract and convert high resolution digital audio data to analog audio signals, audio DAC chips are one of the most important components for determining the quality in audio equipment.
Most electronic equipment incorporates DC-DC conversion in some form. The switched-mode technique is an efficient solution which enables step up and step down in voltage as well as isolation, with small magnetics. This article gives a broad review of the technology and some commercial implementations.
In the final of our four-part series highlighting the shortage and importance of analog design engineering skills, we explain how it’s possible to quickly design a fully functional analog filter circuit without manually calculating component values, using complex numbers or differential equations.
In our series on Audio Technologies, DSP Concepts contributed a blog on Building Voice Assistants for Home Audio, followed by both Fundamentals of Voice UI: Part I: Building Blocks and Fundamentals of Voice UI: Part II: Designing Optimum Beamformers.
Service robots are widely used in various situations such as logistics / transport, security, cleaning, housework, hobbies / entertainment and care / assistance. Since service robots are used in a wide variety of situations, it is necessary to fulfil many requirements such as smooth communication with humans (HMI), ensuring safety and responding to changes in the real time. In service robots, the role of a sensor is very important. In this article, we will take a vacuum cleaner robots as an example.
The PLE series metal power inductors are high-efficiency, ultra-compact components with low leakage magnetic flux that are effective when operating with small batteries installed in wearable devices.
