Whenever a totem-pole TTL output goes from LOW to HIGH, a high-amplitude current spike is drawn from the Vcc supply. How is this effect corrected to a digital circuit?-A-By connecting a radio frequency capacitor from Vcc to ground.B-By using a switching power supplyC-By connecting a capacitor from Vout to groundD-By connecting a large resistor from Vcc to Vout-A-By connecting a radio frequency capacitor from Vcc to ground.

Question

APTITUDE CRACK · Accepted Answer

The correct option is  A By connecting a radio frequency capacitor from Vcc to ground. The most common technique uses small radio frequency capacitors connected from Vcc to ground essentially to short out these high frequency spikes. This is called power supply decoupling. The capacitor values are from 0.01micro farad to 0.1mcro farad.
