Voltage Controlled Amplifier

crossover cut-off frequency. - 0.3 % THD nominal power; 1% THD continuous power. - Tolerance: +10 %; -5 %. - Continuous power given by RMS Voltage measured on resistive load. - The nominal power of the amplifier is measured upon a battery voltage of 12 Volts with a 4 Ohms load and with all channels in function.

radial (north). As the angle measured from the 0° radial increases, the phase of the variable phase signal lags the phase of the reference signal by the number of degrees of the angle from 0°. The reference and variable phase signals, which are 30 Hz voltages, are carried by RF to make radio transmission and reception possible. The VOR receiving equipment must separate the 30 Hz reference and variable phase signals from the RF carrier and compare the phase of the two signals. The phase difference is indicated

of three main factors or terms: the manipulated variables, disturbances, and the controlled variables (Figure 1-1). Typical manipulated variables are valve position, motor speed, damper position, or blade pitch. The controlled variables are those conditions, such as temperature, level, position, pressure, pH, density, moisture content, weight, and speed, that must be maintained at some desired value. For each controlled variable there is an associated manipulated variable. The control system must adjust

important operating and maintenance (servicing) instructions in the literature accompanying the appliance. The lightening flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

light intensity was controlled by detecting electric signals, it was projected on the screen through the several holes of another Nipkow disk synchronously rotating with the Nipkow disk which side picked up the image. The Figure 1-2-1 a schematic diagram of Nipkow machine TV transmission. After experiment of Nipkow disk, later on Mr. John. L. Baird a Scotland scientist and Mr. C. F. Jenkins USA scientist etc. all improved this disk, and in 1907 they used an electronic amplifier invented by Mr. L.
