everything is a filter

Exploring the unseen signal sculptors

In the world (of signal processing), filters are indispensable. They are everywhere, orchestrating a seamless interaction between devices and systems. Think of coffee filters creating that distinct water drip or street signs, regulating the flow of traffic. In a more specific sense, these unseen signal sculptors play an integral role in our experiences, from enhancing audio production to refining data in computer graphics.

A broader understanding

Comprehending the myriad of ways filters impact our lives enables us to optimize their applications. As we study the intricacies – from analog and digital to linear and non-linear – our appreciation for their transformative powers grows.

Unleashing the potential of filters

In the realm of signal processing, filters act as gatekeepers of quality and efficiency. By fine-tuning signals, they improve communication, provide clearer visuals, and amplify overall performance. By embracing the concept that everything is a filter, we uncover the key to unlocking endless possibilities for innovations.

Shaping sound

The concept of eliminating noise & vibrations with its negative equivalent goes as far back as June 1933, when Paul Lueg filed his patent on “silencing sound oscillations”. Yet active noise control has never found widespread application until recently. Read our case studies to learn how you can use the technology.

Using sound

Sound is stronger than light and carries an abundance of information. To date many factories and robots still are deaf. We are here to provide them with ears and use the information to understand and interact effectively.
