         To draw a bode plot , follow these simple steps: Magnitude Plot: Put the frequency response equation into bode equation form. identify the DC gain value, and mark this as a horizontal line coming in from the far left (where the radial frequency conceptually is zero). At every "zero" break point, increase the slope of the line upwards by 20db/decade. At every "pole" break point, decrease the slope of the line downwards by 20db/decade. at every breakpoint, note that the "actual value" is 3db off from the value graphed. Phase Plot If A is positive, start your graph (with zero slope) at 0 degrees. If A is negative, start your graph with zero slope at 180 degrees (or -180 degrees, they are the same thing). For every zero, slope the line up at 45 degrees per decade when   (1 decade before the break frequency). Multiple zeros means the slope is steeper. For every pole, slope the line down at 45 degrees per decade when   (1 decade b

But CS doesn't need much preparation as compared to II. Coming to II exam, 5,6,7,8; 4 days for preparation. Most of the topics in II are familiar, so 2 days can be used for preparing for MP. MP on 11th NOV; its needs a decent preparation. There are a lot of interfacing topics in it; a lot of solved problems. Then we have 3 days gap between MP and MMT. We can expect a good number of arrears in MMT not only because  its a new subject and no books are available for it but also the fact that its not been handled neatly by the concerned professor. And,

UNIT-I CONTROL SYSTEM MODELING PART-A 1. What is control system? A system consists of a number of components connected together to perform a specific function . In a system when the output quantity is controlled by varying the input quantity then the system is called control system.Type equation here. 2. Define open loop control system. The control system in which the output quantity has no effect upon the input quantity is called open loop control system. This means that the output is not feedback to the input for correction. 3. Define closed loop control system. The control system in which the output has an effect upon the input quantity so as to maintain the desired output values are called closed loop control system. 4. What are the components of feedback control system? The components of feedback control system are plant, feedback path elements, error detector actuator and controller. 5. Distinguish between open lo
