Synchronized versus Sequential Sampling Methods (Multiplexing) for Measurement Systems
on the Sampling Theorem). The following figure shows the basic measurement. The Sample-and-Hold amplifier (S/H) holds the voltage. system structures. prevailing at the instant of the sampling until the AD-. converter has transformed the analog measured value. into its digital representation. The control

Non-contact Temperature Measurement and Control (.pdf)
radiation thermometer known as a radiation pyrometer, and the reading compared with a stabilized voltage representing the desired temperature, or set point. Any difference between the two voltages is amplified and fed to a thyristor solid state controller to correct the infrared intensity, and thereby hold

Putting together a high-tech garage band
and custom software. The adjustable saddles on the bridge of the Variaz 700 hold the piezoelectric pickups (the shiny silver insets the strings cross over). They detect string movement and translate it into an electrical signal, which is then converted to a digital signal and manipulated. The V-Synth from
