The source output is transmitted using two modulation schemes, namely Binary PSK (BPSK) and Quadrature PSK (QPSK). Let and B2 be the bandwidth requirements of BPSK and QPSK respectively. Assuming that the bandwidth of the above rectangular pulses is 10 kHz, B1 and B2 are
Consider the following data. The pre order traversal of a binary tree is A, B, E, C, D. The in order traversal of the same binary tree is B, E, A, D, C. The level order sequence for the binary tree is _________
Consider a binary digital communication system with equally likely 0's and 1's. When binary 0 is transmitted the detector input can lie between the levels -0.25V and +0.25V with equal probability: when binary 1 is transmitted, the voltage at the detector can have any value between 0 and 1 V with equal probability. If the detector has a threshold of 0.2 V (i.e., if the received signal is greater than 0.2 V, the bit is taken as 1), the average bit error probability is

Select the correct answer:
A (a 28 year old man) and B (a 27 year old woman) were in a romantic relationship and were living together. After being in a relationship for nearly three years, A asked B whether they could have sexual intercourse. B said that she would consent to sexual intercourse only if A agreed to marry her. A promised to marry B, and thereafter they had sexual intercourse multiple times over the next three years. Subsequently, B discovered that A was not being faithful to her and was in a relationship with another woman. She broke off the relationship, and sought to initiate criminal proceedings against A. Which of the following offences can A be prosecuted for?
Assertion (A): When there is an evidence of a linear relationship between two variables, it may not always mean an independent-dependent relationship between the two variables.
Reason (R): The casual relationship between the two variables may not imply a reasonable theoretical relationship between the two.
S1: Ingratitude stings strongest where relationship is closest.
P: Expectation turns innocent relationship into commerce.
Q: Human relationship is adulterated with sly commerce.
R: In commerce, of course, give and take is understood.
S: Most relationships are founded on mutual expectations.
S6: From any warm and healthy human relationship expectation of returns has to be weeded out.
