The following RC circuit constitutes an automatic reset network for the counter. At power-up, it resets the counter to 0000, then allows it to count normally:



Predict how the operation of this automatic reset circuit will be affected as a result of the following faults. Consider each fault independently (i.e. one at a time, no multiple faults):



Resistor R1 fails open:

Resistor R2 fails open:

Resistor R3 fails open:

Capacitor C1 fails shorted:

For each of these conditions, explain why the resulting effects will occur.
