(a) Explain in a few sentences the difference between a natural frequency and a resonant frequency. Also clarify why for a specific system or component these frequencies may differ in value.
(b) Explain why accelerometers are generally used in NVH to measure the magnitude of vibrations, rather than velocity or displacement transducers. Also discuss the circumstances when it may be preferable to measure displacement or velocity.
(c) In the analysis of dynamic systems it is sometimes expedient to assume a viscous damping model and in other circumstances to assume a hysteretic damping model. Explain in your own words why this is the case. Do not supply an answer that you don't understand.
(d) It is a rule of modal analysis that every mode of vibration must be different. But for some components there may be natural frequencies that are theoretically identical in value. Explain how these repeated natural frequencies can arise.
The major task of a computer is to carry out instruction execution. The key questions that can be asked in this respect are: (a) how are the instructions provided to computer? And
Q. Define diffrent aspects of a System? The aspects of a System are as below: Organization implies order and structure. It is aprearrangement of components which helps t
What is application software? Give example. Application programs are usually written in a high level programming language, in which the programmer states mathematical or text p
How many address bits are required to represent a 32 K memory ? Ans. 32K = 25 x 210 = 215, Hence 15 address bits are needed; Only 16 bits can address this.
Q. What is Status Control and Registers? Status Control and Registers: These registers can't be used by programmers though are used to control CPU or execution of a program.
Q. Show Error detection mechanism? Error detection mechanism can be described as below: Figure: Error detection and correction
Why cyclomatic complexity is important? Cyclomatic complexity is computed using a graph that verifies the control flow of the program. The nodes of the graph correspond to the
The correction to be applied in decimal adder to the generated sum is ? Ans. 00110 is the generated sum when the correction to be applied in decimal adder. While the 4 bit su
What is synchronous transmission? In synchronous transmission the two units share a common frequency and bits are transmitted continuously at the rate dictated by clock pulses
