ds The following circuit contains three outputs, va(t), vy(t) and v(t). a) Draw a block diagram that clearly describes the structure of the circuit. Your diagram should contain only three blocks each producing the outputs, V, Vy and V. Provide a single sentence for each block describing its function. b) Draw the borders for each block on the sheet to show which elements are contained in each block. c) Suppose v.(t) = A, cos(@t), vy(t) = Ay cos(@t+py), v(t) = A cos(@t+qz). Given that A, - A and Qx = 0, derive expressions for Ay, Oy, Az & Q, in terms of A. d) Given the J-FET characteristics, and component values, calculate A. e) Calculate the values of Ay, Py, Az & Qz & 00. = - -1 Ta R = 2kQ2, Vp=-9 V, Vd(on) = 0.7 V 500 ww 1 F 10 54 12 wwww 10 nF Ve HH 10 www 10 www 20 40 nF www 10 Y 10 Va www 10 KO www
