200]  You are troubleshooting a component on a printed circuit
board in a RADAR system while referencing the following Truth
Table in Diagram EL8B.  What kind of integrated circuit is the
component?
            
a}  D-Type Flip-Flop, 3-State, Inverting.@@
            
b}  Q-type Flip-Flop, Non-Inverting.
            
c}  Q-type Directional Shift Register, Dual.
            
d}  D to Q Convertor, 2-State.

            
201]  A circuit card in a radar system has just been replaced
with a spare card. You notice the voltage level at point E in
Diagram EL8C is negative 4.75 volts when the inputs are all at 5
volts.  The problem is:
            
a}  The 25 K resistor is open.
            
b}  The 100 K resistor has been mistakenly replaced with 
a 50 K resistor.
            
c}  The op amp is at the rail voltage.        

d}  The 50 K resistor has been mistakenly replaced with a 25 K
resistor.@@ 


202]  In the circuit contained in Diagram EL8C, there are five
volts present at points B and C, and there is zero volts present
at points A and D.  What is the voltage at point E?
            
a)  3.75 Volts
            
b)  -3.75 Volts
            
c)  -1.5 Volts.@@
            
d)  4.5 Volts
          
        
203]  What does the schematic in Diagram EL8D represent?

a)  A magnetron circuit.

b)  A klystron oscillator.

c)  An STC circuit.@@

d)  An audio oscillator.


204]  The circuit shown in Diagram EL8E is being used as a time
base generator for a CRT.  How can this circuit be changed to
produce the desired waveform shown?

a)  Increase the resistance of R4.

b)  Increase the resistance of R2.@@

c)  Increase the capacitance of C3.

d)  Decrease the resistance of R2.


205]  It is desired to modify the circuit in Diagram EL8E to
produce trapezoidal sweep voltages for an electromagnetic CRT. 
This can be accomplished by:

a)  Increasing the resistance of R4.

b)  Increasing the resistance of R3.

c)  Connecting a resistor between C3 and ground.@@

d)  Connecting another capacitor in series with C3.
