The built-in potential (diffusion potential) in a p-n junction 1. is equal to the difference in the Fermi-level of the two sides, expressed in volts. 2. increases with the increase in the doping levels of the two sides. 3. increases with the increase in temperature. 4. is equal to the average of the Fermi-levels of the two sides. Which of the above statements are correct? Assuming no ISI, the maximum possible bandwidth of a multimode graded index fiber with 5 MHz, shows the total pulse broadening of 0.1s for the distance of about 12 km. What would be the value of bandwidth length product? A digital frequency converter can be converted to DVM by addition of a suitable An X-Y flip-flop, whose characteristic table is given below is to be implemented using J-K flip-flop. This can be done making X Y Q n+1 0 0 1 0 1 Q n 1 0 $${\overline {\text{Q}} _{\text{n}}}$$ 1 1 0 Given a ferrite material that we shall specify to be operating in a linear mode with B = 0.05 T, let us assume µ r = 50, and calculate the approximate value for magnetization M.
