IIR — Infinite impulse response filter design with examples

Digital filters are essential tools in signal processing, helping us remove unwanted noise or extract useful parts of a signal. Among digital filters, IIR (Infinite Impulse Response) filters are very common because they can achieve sharp frequency responses with relatively low computational cost. In this post, we will walk through the basic design of a simple IIR low-pass filter, starting from an analog filter, converting it to the digital domain, and finally implementing it in Read more

How to remove noise from accelerometer data

Do you have a problem with noisy data obtained from your accelerometer sensor? Learn how to remove noise from accelerometer in short practical example. You will understand digital filtering and learn how to make your measurements smoother. Digital Filters In general, we distinguish two kinds of digital filters FIR (filters with Finite Impulse Response ) and IIR (recurrence filters with Infinite Impulse Response). FIR filters are easier to implement so we try to use them Read more
