3. gain to 70.7% of its midrange value. --- Frequencies are values of frequency at which the RC circuits reduce the voltage 4. In low frequency response of an amplifier if the critical frequencies of the three RC circuits are not all equal, the dominant RC circuit is - ----- 5. fa is the abbreviation of - 6. In the coupling and bypass capacitors can be neglected. 7. 8. frequency. 9. When the negative feedback is applied to an amplifier, its voltage gain is 10. Negative feedback is employed in is used in special areas of tuned circuits, such as radio or communications. is the formula that shows the capacitive reactance varies inversely with
Power Amplifier
The power amplifier is an electronic amplifier designed to maximize the signal strength of a given input. The input signal strength is enhanced to a high enough level to drive output devices such as speakers, headphones, RF (Radio frequency) transmitters, etc. Unlike voltage / current amplifiers, the power amplifier is designed to drive core loads directly and is used as a storage block in the amplifier series.
Maximum Efficiency Criterion
In every field of engineering, there is a tremendous use of the machine and all those machines are equipped for their popular work efficiency so it very much important for operation engineers to monitor the efficiency of the machine, planning engineers to check out the efficiency of the machine before installing the machine and design engineers to design machine for higher efficiency than and then the utility will procure their products that will ultimately lead to profit and loss of the company. It indicates the importance of efficiency right from the initial stage as manufacturing units, intermediate stage as planning coordinators, and end-users stage as a utility.
