  • Circuit Ideas: Setting Up a Low-Power Transceiver
    , and 915 MHz but can be programmed in steps of 250 Hz for operation at other frequencies in the UHF range. The chip operates as a conventional heterodyne receiver. The RF input is converted to an intermediate frequency, then gets filtered and fed to a frequency shift-key demodulator. Demodulated data
  • Adapting Qi-compliant Wireless-power Solutions To Low-power Wearable Products
    components-specifically, matching the smaller-size receiver coils to correspondingly smaller transmitter coils to maintain the best coupling factor. Also important is implementation of appropriate external circuit modifications with the transmitter and low-power receiver to minimize system power losses.
  • Frequency Modulation (FM) Tutorial
    Edwin H. Armstrong, known as one of the founding fathers of radio technology, invented the superheterodyne radio receiver in 1918 and frequency modulation (FM) in 1933 [1]. These two concepts, along with his regenerative circuit technique developed in 1912, formed the basis of radio frequency

    Sampling shift spurs digital receiver gains A new sampling technique may lead to simpler single-chip radio receivers that can be produced without special filters. The circuit technique, described at the International Conference of Signal Processing Applications and Technology here, allows sampling
  • Switch Tips: Electro-Optic Level Switches
    Electro-optic level switches are used to signal the presence or absence of a liquid. They contain an infrared light-emitting diode (LED) and a light receiver. Light from the LED reflects from a prism forming the tip of the device back into the light detector. With no liquid present, most LED light
  • Engineer's Assistant Using a PIC16F84A
    This compact instrument is intended to be a digital laboratory tool for hardware and, in some cases, software debugging. It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver. The only chip used is a PIC16F84A running

    XML derivatives seek to pry open telco switches Derivatives of the Internet's Extensible Markup Language are taking center stage in the effort to force open the formerly closed world of circuit-based switches in the telephone company central office. The advent of tools that leverage Web scripting
  • PC systems Pony up to PCI Express
    of today. Tyco Electronics Corp. connectors for x1, x4, x8, and x16 lanes (The spec reserves x2 lane configurations for cable connections rather than circuit boards). One concept for evolving to the PCI Express format is to devise plug-in boards with both ordinary PCI and Express connections
