The input signal is applied across the ground and the base circuit of the transistor. The output signal appears across ground and the collector of the transistor. Since the emitter is connected to the ground, it is common to signals, input and output. The common-emitter circuit is the most widely used of junction transistor amplifiers.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
Note the Q5 and Q6 emitters coupled to the output. In electronics, emitter-coupled logic ( ECL ) is a high-speed integrated circuit bipolar transistor logic family . ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of ...
Darlington Transistor (NPN-type) In electronics, a Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one.

The primary challenge with the PLC to date is the unshielded and untwisted power wiring. This type of wiring releases significant radio energy, potentially disrupting others using the same frequency band. Additionally, the BPL (Broadband over Power Line) systems may experience interference from the radio signals produced by the PLC wiring. [3]
