A triple pole amplifier exhibits midband and high frequency response characterized by the following information. Open loop gain =11, fH1%=D10KHZ, FH2=300 KHz and fH3=10 MHz. Determine the following: a) What is the midband gain in dB? b) What is the overall cutoff frequency for this amplifier? c) What is the slope of the magnitude portion of the Bode plot between 30OkHz- 10MHZ? d) What is the ending phase of the Phase portion of the phase plot? e) Sketch the magnitude and phase portions of the Bode plots.
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.
