THE FASTEST FOURIER TRANSFORM IN THE WEST

THE FASTEST FOURIER TRANSFORM IN THE WEST

An interesting aspect of time-varying waveforms is that by using a trick called a Fourier Transform (FT), they can be represented as the sum of their underlying frequencies. This mathematical insight is extremely helpful when processing signals digitally, and allows a simpler way to implement frequency-dependent filtration in a digital system. [klafyvel] needed this capability […]

WORLD’S FIRST MOS FET RELAY MODULE “G3VM 21MT” WITH SOLID STATE RELAY IN “T TYPE CIRCUIT STRUCTURE”

WORLD’S FIRST MOS FET RELAY MODULE “G3VM-21MT” WITH SOLID STATE RELAY IN “T-TYPE CIRCUIT STRUCTURE”

OMRON Corporation of Kyoto, western Japan globally released its new MOS FET (*1) relay module “G3VM-21MT” on December 2, 2019. The product is the first electronic component in the world (2) to adopt a “T-type circuit structure” (3). With a T-type circuit structure consisting of compact-size and longer-lifecycle solid-state relays that output signals using no physical contact, the relay

4 Methods to Choose Your Right Phased Array Transducer

Introduction Modern phased array transducers for industrial NDT are usually made from piezocomposites, which in turn consist of many small thin segments of piezoelectric ceramic embedded in a polymer matrix. Phased Array Transducer comes in a wide variety of shapes, sizes, frequency ranges, and a number of elements. This technology is most often used to

THE APOLLO DIGITAL RANGING SYSTEM MORE THAN MEETS THE EYE

THE APOLLO DIGITAL RANGING SYSTEM: MORE THAN MEETS THE EYE

If you haven’t seen [Ken Shirriff]’s teardowns and reverse engineering expeditions, then you’re in for a treat. His explanation and demonstration of the Apollo digital ranging system is a fascinating read, even if vintage computing and engineering aren’t part of your normal fare. The average Hackaday reader should be familiar with the concept of determining the distance

NTP RUST AND ARDUINO MAKE A PHENOMENAL FREQUENCY COUNTER

NTP, RUST, AND ARDUINO MAKE A PHENOMENAL FREQUENCY COUNTER

Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum frequency is however limited to a fraction of the microcontroller’s clock speed and the accuracy of the resulting instrument depends on that of the clock
