Furthermore, each parasitic resistance of the ground wirings and the like is depicted by a circuit symbol of a resistor. In this figure, resistances 501 and 502 represent parasitic resistances of the ground wiring 20. The resistance 501 is a parasitic resistance between the point P and the ...
The typical application diagram of data converters will often show a zener diode symbol representing the reference, indicating the use of a shunt reference. This is merely a convention, and in nearly all cases a series reference could be used as well. Voltage reference specifications As with all...
is projected or in the vicinity of the plane closest to the scanner in which it is desired to read a coded symbol. In the far field, the beam diverges at an angle which is approximately inversely proportional to the effective aperture of the beam. This effective aperture is preferably provid...
