[Ideas For Design]
Varactor diode stabilizes temperature for FM quadrature demodulator
A quadrature detector is used to demodulate frequency shift keying (FSK) and other types of FM signals. The MC13156 shown is an FM subsystem integrated circuit that downconverts the RF to a 10.7-MHz intermediate frequency (IF), amplification, and...  — Contributing Author

Linear pitot-tube air-speed indicator
Among the many methods used for measuring air speed, one approach excels in applications related to aerodynamics and wind power: the Pitot-tube impact-pressure air-speed indicator. The so-called “impact” or “stagnation” pressure exerted by airflow...  — W. Stephen Woodward

A fluid solution for water-tank pressure sensing
Liquid sensors require a media-compatible, solid-state pressure sensor. The pressure range of the sensor depends on the height of the column or tank of fluid that must be sensed. Described here is a way to sense water height in a tank or column using...  — Contributing Author
