    TI resolver interface offers integration benefits in industrial drives and HEV/EV

    Many motor-drive applications (see Figure 1) typically need a position/speed feedback loop to ensure efficient system performance. For users to meet their accuracy needs there are many different technologies for position/speed sensing on the market t...

    Digital signal processing in RF sampling DACs – part 2

    In this blog post, I will describe mixers and numerically controlled oscillators (NCOs), which are the basic building blocks used to implement digital up converters (DUCs) in the RF sampling digital-to-analog converter (DAC) signal chain. In the previous installment of this series, I explained the use of interpolation filters to increase the data...

    RS-232: Use this old dog for new tricks

    The other day, as my dad was guiding me on a tour of his metal manufacturing shop, we stopped at a computer numerical control (CNC) machine, like that seen in Figure 1 that’s just about as old as I am. After unscrewing a latch, he revealed none...

    Understanding radiation reports: the low down on particle LET

    There are high levels of radiation in space, primarily electrons, protons and heavier ions. When an energetic particle travels through matter (like silicon), it suffers numerous interactions that extract some of its kinetic energy. The energy lost ...

    Can a clock generator act as a jitter cleaner?

    I’m excited to have the opportunity to address clock generators and jitter cleaners. My goal is that after reading this post, you will not stereotype a clock generator as a device that can’t also perform jitter cleaning. I will discuss the difference between clock generators and jitter cleaners, cover some key points about phase-locked loops...

    Professional audio equipment made the most noise at the 2017 NAMM Show

    Guitars, drums, cymbals … the 2017 National Association of Music Merchants (NAMM) Show had it all, but what seemed to be making the most noise was the professional audio gear. I’ve heard a lot about the NAMM Show, the largest music gear conference in the U.S. (probably the world), and my excitement attending for the first time was hard...

    What are the building blocks of Bluetooth speakers?

    Bluetooth® speakers are now fairly common in the marketplace. Many manufacturers offer very basic systems selling for a few dollars to high-end systems selling for hundreds, with varying degrees of audio performance. The Bluetooth market is highl...

    Digital signal processing in RF sampling DACs - part 1

    In this blog post, I will discuss the important digital signal processing (DSP) blocks that create all of the magic in direct RF sampling DACs. These blocks include interpolation filters, mixers, numerically controlled oscillators (NCOs), summers and inverse sinc filters. What makes RF sampling devices magical is that they combine digital interpolation...

    RF sampling: Learning more about Latency

    In this post, I’m going to discuss latency in an analog-to-digital converter (ADC). Latency is the time it takes for a signal to travel from point A to point B. In an ADC, latency is how long it takes from the time that an analog input is applied to the time that the digital output word becomes available. Why is latency important? Regardless...
