Q. The correct circuit representation of the structure shown in the figure is Ans: Option A Points to note to solve this question. 1) Emitter and collector are n-type so the transistor will be n-p-n ∴ Options (3) and (4) are eliminated 2) The diode is connected ...

Q. Which one of the following options describes correctly the equilibrium band diagram at T=300 K of a Silicon pnn+p++ configuration shown in the figure? Ans: Option A.

Q. A linear Hamming code is used to map 4-bit messages to 7-bit codewords. The encoder mapping is linear. If the message 0001 is mapped to the codeword 0000111, and the message 0011 is mapped to the codeword 1100110, then the message 0010 is mapped to (A) 0010011 (B) 1100001 (C) 1111000 ...

Q. For an LTI system, the Bode plot for its gain is as illustrated in the figure shown. The number of system poles 𝑁𝑝 and the number of system zeros 𝑁𝑧 in the frequency range 1 Hz ≤ 𝑓 ≤ 107 Hz is (A) 𝑁𝑝 = 5, 𝑁𝑧 = 2 (B) 𝑁𝑝 = 6, 𝑁𝑧 = 3 (C) 𝑁𝑝 = 7, 𝑁𝑧 = 4 (D) 𝑁𝑝 = 4, 𝑁𝑧 = 2 Ans: Np ...

Q. Consider the two-port resistive network shown in the figure. When an excitation of 5 V is applied across Port 1, and Port 2 is shorted, the current through the short circuit at Port 2 is measured to be 1 A (see (a) in the figure). Now, if an excitation of 5 V is applied across Port 2, and ...

Q. Which one of the following functions is analytic over the entire complex plane? Ans: cos (z)

Q. Two design consultants, P and Q, started working from 8 AM for a client. The client budgeted a total of USD 3000 for the consultants. P stopped working when the hour hand moved by 210 degrees on the clock. Q stopped working when the hour hand moved by 240 degrees. P took two tea breaks of 15 ...

Q. “Indian history was written by British historians – extremely well documented and researched, but not always impartial. History had to serve its purpose: Everything was made subservient to the glory of the Union Jack. Latter-day Indian scholars presented a contrary picture.” From the text ...

Q. The bar graph in Panel (a) shows the proportion of male and female illiterates in 2001 and 2011. The proportions of males and females in 2001 and 2011 are given in Panel (b) and (c), respectively. The total population did not change during this period. The percentage increase in the total ...
