LIMITATION OF SIGHT AND HEARING INTRODUCTION Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as microphone‚ stethoscope‚ earphone

Oscilloscope _ An oscilloscope (also known as a scope‚ CRO‚ DSO or‚ an O-scope) is a type of electronic test instrument that allows observation of constantly varying signal voltages‚ usually as a two-dimensional graph of one or more electrical potential differences using the vertical or ’Y’ axis‚ plotted as a function of time‚ (horizontal or ’x’ axis). Although an oscilloscope displays voltage on its vertical axis‚ any other quantity that can be converted to a voltage can be displayed as well

the reciprocal of the frequency. Impedance- is the measure of the opposition that a circuit presents to a current when a voltage is applied. In quantitative terms‚ it is the complex ratio of the voltage to the current in an alternating current (AC) circuit. Impedance extends the concept of resistance to AC circuits‚ and possesses both magnitude and phase‚ unlike resistance‚ which has only magnitude. When a circuit is driven with direct current (DC)‚ there is no distinction between impedance and resistance; the

Research about LM317 Positive Adjustable Linear Voltage Regulator: The LM317T is a 3-terminal integrated circuit which can supply a load current of up to 1.5 Amps with an output voltage of between 1.2V and 37 Volts. It accepts an input voltage of between 3 and 40 volts. It can be used to regulate either current or voltage in situations where a fixed current or fixed voltage is required. The level of current or voltage required can be adjusted by connecting the chip in series with a fixed resistor

A direct box (DI) can be used when the guitar amplifier is small and produces a thin sound. The DI takes an unbalanced‚ high impedance signal and converts it to a balanced‚ low impedance signal. The signal is able to travel over long cables with less signal loss. The DI boxes include filters to emulate speaker response and can be connected directly to the extension speaker outlet of the amplifier. The Live
