 We can use RC circuits to not only charge but also discharge capacitors. Assume we connect a battery to an...

What is an RC Circuit? An RC circuit contains both resistance and capacitance. The capacitor, as described in Capacitance, is...

What is a MOD Counter? A Modulus-M Counter is a counter in which M represents the number of states present....

A BCD counter is a 4-bit binary counter that counts from 0 to a predetermined count using a clock signal....

Synchronous refers to something that is time-synchronized with others. Synchronous signals occur at the same clock rate, and all clocks...

Asynchronous counters are those that do not use simultaneous clocking. Only the first flip-flop in an asynchronous counter is externally...

Frequency-Division-Divide-by-2-Counter In the Sequential Logic D-type Flip-Flops can be connected to form a Data Latch. The D-type Flip-Flop is also...

A Schmitt trigger is a comparator circuit with hysteresis implemented by applying positive feedback to a comparator or differential amplifier's...

What is a Notch Filter? A notch filter (also known as a bandstop filter or reject filter) is a device...

A Triac is a medium- to high-power semi-latching solid-state AC power switch that can be controlled. This two-part article explains...
