Here is the answer key
to November's puzzle:
LASER DISC OPTICS
IN
70. Why are integrated circuits divided into two categories ( digital and linear)?
a. These names refer to two general types of packages.
b. These are the two temperature ranges or grades into which ICs are
classified by testing.
c. I Cs are simply circuits that happen to be constructed integrally, and like all
circuits, are either switching-type or amplifying-type.
d One type processes infonnation and the other controls large working
devices such as motors.
e. ICs are used for either input purposes or output purposes.
71. What advantages do I Cs have over discrete-device circuits due to their greater
complexity (more circuitry in less area)?
a. Smaller size
b. Higher reliability
c. Better overall perfonnance
d Lower cost
e. All but c above
72. What are the limitations of integrated circuits?
a. Not all electronic components can be efficiently integrated into a silicon
chip.
b. ICs are generally more expensive than their discrete-device counterparts.
c. ICs are limited to rather low voltages.
d ICs can stand a relatively small amount of power dissipation (heating).
e. All but b above.
73. Which of the following common electronic components is not found in
ordinary ICs?
1. Inductors
b. Diodes
c. Resistors
d Transistors
e. Low-capacitance capacitors
74. Why is the plastic dual-in-line package the most popular IC package?
a. It is low in cost.
b. It is easy to insert and solder into printed wiring boards by means of
automatic handling equipment.
c. Its solid construction makes it ruggedly resist vibration and impact.
d It is one of the smallest possible packages.
e. All but d above.

Distributor-sponsored S*TJ Technical Seminars are available at no cost to any
distributors interested in assisting their clients to understand operation and
maintenance of videos, pins and lasers.
The 5-day course covers Basic Electronics ( electron theory and semicon-
ductors ), Video Game Systems (power supplies, control panel interfaces, rasterscan
and X-Y monitors), Electronic Pinball Systems (electronic digital systems),
Troubleshooting Techniques, Test Equipment ( digital multimeters and logic
probes), Proper Soldering Techniques, Laser Disc Operation and Maintenance,
How to Read Electronic Schematics and other essential skills.
If you'd like to sponsor an S*TJ Technical Seminar, contact Star*Tech
Journal at 609/662-3432 and ask for our infonnation package. This package helps
you plan your promotion for a successful seminar.
