www2.mvcc.eduAC, or alternating current, is so named because the current alternates or flips back and forth between two polarities. In other words, the current (and consequently the voltage) is a function of time. This is fundamentally different from direct current that ... AC circuits.. DC DC DC DC DC DC DC ()) ()) ...

eie.uonbi.ac.kechange at any time in response to an input change. Asynchronous circuits are tricky to design, and so most sequential logic circuits are designed in a slightly different way, as synchronous circuits. In a synchronous sequential circuit, changes of state are only allowed to happen at times synchronous to a special timing signal, called the clock.

www.seas.ucla.eduSuch circuits are called “discrete-time” or “sampled-data” ... providing dc feedback while negligibly affecting the ac behavior of the amplifier in the frequency band of interest. Such an arrangement is indeed practical if the circuit senses only high-frequency signals. But suppose, for example, the circuit is to amplify a voltage

If fact signals travel at around half the speed of light (c = 30 cm/ns). Reason: all wires have capacitance to ground and to neighbouring conductors and also self-inductance.
