Why an op-amp diode rectifier called as a precision rectifier?
In a rectifier made of just diodes, the diodes have a voltage drop, resulting in a lower DC output voltage. By introducing an Op-amp, this voltage drop can be overcome. Since there is no voltage drop caused by the diodes, the rectified signal is not changed by the rectifier, so it is called a precision rectifier.

How can you tell if the head unit output signal is to strong for the amp?
if the head unit can produce sound to your speakers without the amp you have high level output from head unit if your amp only accepts low level input (rca) plugs you must buy a high to low level converter which take speaker high output and reduces it to low ( rca) output and then go to your amp converter is under 20 bucks but most new amp accept hi and low level feed

What is the name of the meter that is used to measure current?
Give the definition of output offset voltage of Op-Amp?
Why clipping happen for op-amp?
Clipping occurs in the voltage waveform when the input voltage, multiplied by the voltage gain of the op-amp circuit, exceeds the op-amp supply voltage as limited by the output network. The supply voltage and output network, limits the maximum voltage that can be achieved at the output. The op-amp behaves normally within its range of maximum voltage output, and then it is clipped when it reaches the maximum voltage of the circuit.

What regulates voltage for mercury outboard?
It would depend on the stator used. On the 9 amp stator, a regulator is not used due to the low voltage output, this system has a rectifier only. The 16, 32, and 40 amp systems may use single, or dual regulators to both regulate, and rectify the current from AC to DC voltage. To determine which system you have, follow the two yellow wires down from under the flywheel, where the stator is mounted, to either the rectifier, or the regulator. Note: The 40 amp stator will have two sets of yellow wires connected to the dual regulators.

Asked in Electronics Engineering
What isDifference between ordinary rectifier and precision rectifier?
A simple rectifier circuit uses a diode and there is a turn ON voltage for the diode. The input voltage has to exceed the turn ON voltage (0.6V for ordinary Si diode) before rectification is achieved. A precision rectifier is an active circuit using an opamp and a diode in the feedback loop. This overcomes the turn-on "knee" voltage. The op amp reduces the turn-on voltage of a diode in its feedback loop by a factor equal to the open-loop gain of the op amp. For practical op amp gains this reduces the forward voltage to a fraction of a mV, thus giving a "precision" or near ideal diode characteristic for the rectifier function.
