Plot the pixel histogram( take any image) – count of values versus pixel intensity 0 to 255. You must write this from first principles – do not use the MATLAB hist command (although you may use it for comparison and checking your algorithm’s correctness). Plot the cumulative histogram. Do not use the cumsum function in MATLAB (write your own function to achieve this).
2070Hello sir, I am Rajaram. I have finished DME (Diploma in Mechanical Engineering). I would like to attend BHEL supervisor examination. So i want which type of questions can i prepare. & give previous supervisor examinations questions. Reply my mail (rajaramsptc@gmail.com)
Bhel,

What is meant by D-FF? What is the basic difference between Latches and Flip flops? What is a multiplexer? How can you convert an SR Flip-flop to a JK Flip-flop? How can you convert an JK Flip-flop to a D Flip-flop? What is Race-around problem? How can you rectify it? Which semiconductor device is used as a voltage regulator and why? What do you mean by an ideal voltage source? What do you mean by zener breakdown and avalanche breakdown? What are the different types of filters? What is the need of filtering ideal response of filters and actual response of filters? What is sampling theorem? What is impulse response? Explain the advantages and disadvantages of FIR filters compared to IIR counterparts. What is CMRR? Explain briefly. What do you mean by half-duplex and full-duplex communication? Explain briefly. Which range of signals are used for terrestrial transmission? What is the need for modulation? Which type of modulation is used in TV transmission? Why we use vestigial side band (VSB-C3F) transmission for picture? When transmitting digital signals is it necessary to transmit some harmonics in addition to fundamental frequency? For asynchronous transmission, is it necessary to supply some synchronizing pulses additionally or to supply or to supply start and stop bit? BPFSK is more efficient than BFSK in presence of noise. Why? What is meant by pre-emphasis and de-emphasis? What do you mean by 3 dB cutoff frequency? Why is it 3 dB, not 1 dB?
