  • TC7136/TC9400 Digital Readout Frequency Meter
    Two low-cost integrated circuits can be combined to create a simple digital frequency meter. The combination of a frequency-to-voltage converter (FVC) and a dual-slope, analog-to-digital display converter (ADC) makes a small 2-chip frequency meter that can be run from one 9-volt battery

  • Copper Cabling for Digital Audio and Video Applications
    Much of the newest audio and visual (A/V) hardware is digital rather than analog, providing benefits of faster processing speeds, lower cost connectivity, improved reliability, less noise, and truer reproduction. This article discusses various digital A/V applications and examines how commercial
