Prove the following statement: Let \{a_i\} and \{b_i\} be two sequences of real numbers such that either $a_1 \le a_2 \le \dots \le a_n$, $b_1 \le b_2 \le \dots \le b_n$ or $a_1 \ge a_2 \ge \dots \ge a_n$, $b_1 \ge b_2 \ge \dots \ge b_n$ If \{\lambda_i\} is a sequence of non-negative numbers such that $\sum_{i=1}^n \lambda_i = 1$ then $\left(\sum_{i=1}^n \lambda_i a_i\right)\left(\sum_{j=1}^n \lambda_j b_j\right) \le \sum_{i=1}^n \lambda_i a_i b_i$

Section-3 (16 marks question) Q. 7. For a class-AB power amplifier biased using diodes as shown in Fig. Q7, following information is given: Junction areas of QN and Qp are twice that of the diodes, Vcc = 10 V, RL = 100 Ohms, Output is sinusoid with maximum amplitude of 10 V, Diodes and BJT's have reverse saturation current parameter $I_s =$ $10^{-12}$ A, $\beta$ for both transistors is 100. Calculate the following quantities: (a) The bias current $I_{BIAS}$ which guarantees 1 mA current flowing through the diodes at all times. 4 marks (b) The quiescent power dissipation in the output transistors. 4 marks (c) Efficiency of this power amplifier circuit. 4 marks (d) The currents $i_N$ and $i_P$ through the transistors QN and QP when output is +10 V and -10V respectively. 4 marks
