A circuit card in a RADAR system has just been replaced with a spare card. You notice the voltage level at point E in Fig. 8F12 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.
