    en.wikipedia.org/wiki/Electronic_musical_instrument

    An electronic musical instrument is a musical instrument that produces sound using electronic circuitry.Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.

    • 1) Absolute instruments :: These absolute instruments give the magnitude of the quantity under measurement in terms of physical constants of the instrument.These absolute instruments are standard and are used laboratories.Examples of these instruments are tangent galvanometer Rayleigh's current balance.These absolute instruments have a very good article in wiki pedia.
    • 2) Secondary instruments :: These instruments are so constructed that the quantity being measured can only be measured by observing the output indicated by the instrument.
    • 1) Deflection type instruments:: In these deflection types instruments, the deflection of the instrument provides a basis for determining the quantity under measurement.
    • 2)Null type instruments:: In these null type instruments, a zero or null Indication leads to determination of the magnitude of measured quantity.In contrast to deflection type instruments, a null type instrument attempts to maintain the deflection at zero by suitable application of an effect opposing that generated by the measured quantity.

    These instruments give output in terms of physical constant of the instruments. For example Rayleigh’s current balance and Tangent galvanometer are absolute instruments.

    These instruments are constructed with the help of absolute instruments. Secondary instruments are calibrated by comparison with absolute instruments. These are more frequently used in measurement of the quantities as compared to absolute instruments, as working with absolute instruments is time consuming. Another way of classifying the electrical measuring instruments depends on the way they produce the result of measurements. On this basis they can be of two types:

    In these types of instruments, pointer of the electrical measuring instrument deflects to measure the quantity. The value of the quantity can be measured by measuring the net deflection of the pointer from its initial position. In order to understand these types of instruments let us take an example of deflection type permanent magnet moving coil ammeterwhich is shown below: The diagram shown above has two permanent magnets which are called the stationary part of the instrument and the moving part which is between the two permanent magnets that consists of pointer. The deflection of the moving coil is directly proportion to the current. Thus the torque is proportional to the current which is given by the expression Td = K.I, where Tdis the deflecting torque. K is proportionality constant which depends upon the strength of the magnetic fieldand the number of turns in the coil. The pointer deflects between the two opposite forces produced by the spring and the magnets. And the resulti...

    In opposite to deflection type of instruments, the null or zero type electrical measuring instruments tend to maintain the position of pointer stationary. They maintain the position of the pointer stationary by producing opposing effect. Thus for the operation of null type instruments following steps are required: 1. Value of opposite effect should be known in order to calculate the value of unknown quantity. 2. Detector shows the balance and the unbalance condition accurately. The detector should also have the means for restoring force. Let us look at the advantages and disadvantages of deflection and null type of measuring instruments: 1. Deflection type of instruments is less accurate than the null type of instruments. It is because, in the null deflecting instruments the opposing effect is calibrated with the high degree of accuracy while the calibration of the deflection type instruments depends on the value of instrument constant hence usually not having high degree of accurac...

    These instruments provide information regarding the variable quantity under measurement and most of the time this information are provided by the deflection of the pointer. This kind of function is known as the indicating function of the instruments.

    These instruments usually use the paper in order to record the output. This type of function is known as the recording function of the instruments.

    This is function is widely used in industrial world. In this topic these instruments controls the processes. Now there are two characteristics of electrical measuring instruments and measurement systems. They are written below:

    In these type of characteristics measurement of quantities are either constant or vary slowly with the time. Few main static characteristics are written below: 1. Accuracy: It is desirable quality in measurement. It is defined as the degree of the closeness with which instrument reading approaches the true value of the quantity being measured. Accuracy can be expressed in three ways 1.1. Point accuracy 1.2. Accuracy as the percentage of scale of range 1.3. Accuracy as percentage of true value. 2. Sensitivity: It is also desirable quality in the measurement. It is defined as the ratio of the magnitude response of the output signal to the magnitude response of the input signal. 3. Reproducibility: It is again a desirable quality. It is defined as the degree of the closeness with which a given quantity may be repeatedly measured. High value of reproducibility means low value of drift. Drift are of three types 3.1. Zero drift 3.2. Span drift 3.3. Zonal drift

    These characteristics are related with the rapidly changing quantities therefore in order to understand these types of characteristics we are required to study the dynamic relations between the input and the output.
