| Abstract | The real beginning in electronics was made in 1906, when Lee De Forest invented vacuum triode. Without this device, the amplifier which is the heart of all intricate and complex electronic gadgets would not have been possible. Until the end of World War II, the vacuum tubes dominated the fields of Electronics. Instrumentation plays very important in any industry and research organization. Electronics deals in the micro and milli range of voltage, current and power, but it is capable of controlling kilo and mega volts, amperes and watts. Therefore, it is not surprising to find the fundamentals of electronics as a core subjects in all branches of engineering nowadays. |

| Abstract | We know that in a communication system, a radio transmitter radiates or transmits a modulated carrier signal. This modulated carrier signal travels down the channel i.e. transmission medium and reaches at the input of radio receiver. This means that the modulated carrier signal is picked up by the antenna of the radio receiver. This modulated signal so received is generally very weak. Therefore, inside the receiver this weak signal is first amplified in an R.F. (Radio frequency) amplifier stage of the radio receiver. Also, since the received modulated signal contains a lot of noise or unwanted signals at adjacent frequencies, it must be selected and the noise must be rejected. Finally, in receiver, the R.F. carrier or modulated signal must be demodulated to get back the original modulating or baseband signal. Further, since the demodulated or detected signal (i.e. audio signal in case of broadcast receiver) is generally weak, it has to be amplified in one or more stages of audio amplifier. |

| Abstract | A practical amplifier circuit is meant to raise the voltage level of the input signal. This signal may be obtained from the piezoelectric crystal of a record player, the sound head of a tape recorder, the microphone in case of a PA system, or from a detector circuit of a radio or TV receiver. Such a signal is not of a single frequency. But it consists of a band of frequencies. For example, the electrical signal produced by the voice of human being or by a musical orchestra may contain frequencies as low as 30 Hz and as high as 15 kHz. Such a signal is called audio signal. If the loudspeakers are to reproduce the original sound faithfully, the amplifier used must amplify all the frequency components of the signal equally well. If it does not do so, the output of the loudspeaker will not be an exact replica of the original sound. When this happens, we say that distortion has been introduced by the amplifier. |

| Abstract | In this Paper, introducing the methods for designing a fault-detection experiment for sequential circuits or machines. In Sequential circuits, the fault testing and diagnosis is complicated by presence of memory. So, two distinctly different approaches were developed to solve the problem of fault detection in sequential circuits. |
