Beamforming arrays let designers create directional microphones using MEMS devices. With the right signal processing algorithms, these can enhance the user experience delivered by many types of audio equipment. An array can be simple, comprising as few as two microphones, and can be arranged in various configurations depending on the expected location of the preferred […]

Choosing the right MEMS microphone interface for your project
Micro-electro-mechanical systems (MEMS) microphones have been steadily increasing their market share, driven by the surge in popularity of voice-controlled electronics with applications like voice-enabled navigation devices and digital home assistants. But what are the different types of MEMS microphone electrical interfaces available and how do you apply them to your application? A MEMS microphone with […]
Choosing the right encoder – open-collector, push-pull or differential output?
Position encoders are widely used in motion control applications and many different types are available. To choose the optimum device for a given application, engineers must decide between absolute, incremental or commutation encoders, which present data in various formats such as quadrature, motor-pole or a serial protocol. The resolution required, as well as dimensions and […]
