Harmonics of a signal are signals which are related to the original or fundamental by an integer non decimal number. A pure tone sine wave signal has no harmonics; it consists of only one single frequency. If pure tone signal was applied to the input of an amplifier, we would upon measurement with special test equipment find that the output signal of the amplifier was no longer pure. Careful measurements would likely show that several new frequencies have appeared. These new frequencies are almost certainly to be integer multiples of the original tone; they are the harmonics of the original signal.

In a good amplifier, the harmonics will be much weaker than the original tone. By much weaker, we mean on the order of a thousand times for decent amplifiers. Intermodulation distortion is the second major type of distortion that is often specified for amplifiers.

Intermodulation distortion is much more objectionable to the human ear, because it generates non-harmonically related extra signals which were not present in the original. Basically, two pure tones are simultaneously applied to the input of the amplifier.

If the amplifier were perfect, the two tones and only the two tones would be present at the amplifier output. In the real world, the amplifier would have some harmonic distortion as described above , but careful observation of the output signal using laboratory equipment would reveal that there are a number of new tones present which cannot be accounted for as a result of harmonic distortion. These new tones are called beat products or sum and difference frequencies, and are a result of the interaction of the two pure tones within the amplifier.

No amplifier is perfect, all have some non linear characteristics. Whenever two signals are applied to a nonlinear system, new signals in addition to the original two are generated.

For a good amplifier, the new signals are very small in relation to the two original tones. All amplifiers are generally rated for Total Harmonic Distortion or THD , usually at full power output over a given frequency band with a particular load. Good values are anything less than 0. When an amplifier is measured for THD, a pure tone is applied to the input and the output is measured with special test equipment.

The energy of the pure tone is measured, and the energy of the harmonics is measured. Those two values are compared, and a THD rating is calculated. Harmonic distortion although certainly undesirable is one of the more tolerable types of distortion as long as it is kept reasonably low.

Therefore, for reduction of nonlinear distortions target capacity of the amplifier are artificial limit in comparison with the greatest possible output power. As sensitivity of the amplifier understand value of the sine wave input voltage, necessary for obtain of the maximal output power.

Frequently, some manufacturers indicate value of a nominal input voltage. A nominal input voltage is a sine wave voltage applied to an input of the amplifier for obtain of nominal output power. Subject to credit approval.

The preamplifier section of this circuit is based around Q4 and Q5 which forms a differential amplifier. The use of a differential amplifier in the input stage reduces noise and also provides a means for applying negative feedback.

Thus overall performance of the amplifier is improved. Input signal is applied to the base of Q5 through the DC decoupling capacitor C2.

Feedback voltage is applied to the base of Q4 from the junction of 0.

A complementary Class AB push-pull stage is built around the transistors Q1 and Q2 for driving the loud speaker. Transistor Q3 drives the push-pull pair and its base is directly coupled to the collector of Q5. We shall upload a sample PCB file for download shortly. They are shown as conventional transistors in figure for ease. Even though each of them have 2 transistors ,2 resistors and 1 diode inside ,only three pins ,base emitter and collector are coming out.With reference to consumer and professional electronics equipments, the greatest popularity are the integrated circuits- power audio amplifiers, due to their advantages - schematic simplicity, small dimensions, large range of output powers, functionality.

You must try this circuit. Alpha-numeric index 2. If the range of frequencies is not underlined, own noise are measured within the limits of a working range of frequencies of the amplifier.
