ECE102 Quiz 2 – Question Pages Fall 2009 1 Student ID Name (Last, First) Write your answers on the separate answer pages; we will not look at these question pages. Question 1 (2 + 2 = 4 points): (a) Consider a linear system that has output V out1 when the input is V in1 : V in1 (V) = 1 + 4 sin(9 t) + 5 10 -3 sin(5 10 8 t) + sin(10 6 t) V out1 (V) = 2 sin(9 t) + 15 10 -3 sin(5 10 8 t + π /2) + 5 sin(10 6 t + π /4) What is the output V out2 of this system when the input is V in2 (V) = 100 + 5 sin(9 t) + 4 sin(5 10 8 t) ? (b) What is the reason most linear systems (such as communication systems or amplifiers) use sine and cosine waves as inputs? Be brief (1 sentence). Question 2 (4 + 1 + 1 = 6 points): Consider the MOSFET circuit below. (a) Find V 1 when resistor R 1 = 1 k . (b) What is the minimum value of R 1 such that the nMOS operates in saturation? (c) What is the maximum
