Hardware Conditioning of Sensor Signals


Recording Date: 04/04/2008
Duration: 32 min

Abstract

This webinar explains the analog hardware conditioning we require for sensor signals before they can be digitally processed by an embedded processor such as the Digital Signal Controllers from Microchip Technology. First, we will look at a type of analog filters called Anti-aliasing Filters, understand the benefits of using these filters and how to design them. We will then move on to the broad subject of how to suitably amplify the sensor signals using various techniques and classes of amplifiers. Finally, we will explore some signal conditioning considerations that come into play when we need to interface the filtered and amplified sensor signals with an Analog-to-Digital Converter, or ADC, which is often on on-chip peripheral module within the DSC or MCU device.

PresenterPriyabrata Sinha, Principal Applications Engineer, DSC Division

Priyabrata Sinha (Priyo) obtained his Bachelors degree in Electronics and Telecommunication Engineering from the University of Pune (India) in 1998, followed by a Masters in Electrical and Computer Engineering from the University of Florida in 2000. Since then he has been working as an Applications Engineer specializing in the dsPIC30F family of Digital Signal Controllers. His fields of concentration include application development and support in various Digital Signal Processing (DSP) application areas, as well as microcontroller architectures and peripherals like Controller Area Network (CAN).
