Qu 2. Generate Bode Plots of the transfer functions given below. Use them to obtain the following information. 12 12500 G(s)= G(s)= s² +0.4s +4 s³+102s +225s +2500 a) Gradients of the magnitude response (before and after each break frequency); b) Values of break frequencies or peak frequency: c) DC Gain (k): d) Phase shifts before and after each break frequency: e) Factorise the denominator (confirm that the transfer functions are made up of 2nd order systems and possibly also a 1st order system), obtain the generic 2nd order and 1st order forms of the denominator, and confirm the values of undamped natural frequency, damping ratio and gain (for 1st order system components, time constant as well) with the values obtained from 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.
