A voltage amplifier does not have to supply significant current bur a power amplifier does.
It doesn't. You can make a differential amplifier with a single power supply.
is an embedded circuit or stand alone unit the function of which is to supply a stable voltage to a circuit or device that must be operated within certain power supply limits .
Power supply, oscillator, modulator, and amplifier.
It is the power supply terminal.
The battery charger can be used but it is not recommended. The battery charger does not have filtering on the its output like a power supply does. You will probably hear an AC ripple on the amplifier which will become very annoying when listening to the amplifier.
Yes, you need a cable to connect the power supply to the amplifier, but the specific type of cable required depends on the model and power requirements of the amplifier. In most cases, a standard power cord with the appropriate voltage and current rating will suffice. It's always recommended to refer to the amplifier's user manual for the correct power supply requirements.
used to increase the power level of the transmitting signal
The PC power supply box's function is to supply the computer with power. Without the PC power supply box, the computer would not be able to turn on and off.
It just implies the built-in amplifier function power capability of the HU.
Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
The supply of power to that city.
