A prehistoric homo erectus woman is interested in surviving the harsh environment. One night by the campfire, she hears a rustle in the bushes. She hypothesizes that there is a predator in the bushes. If there is a predator, she and her tribe would like to move to shelter which will result in losing her dinner. If there is not a predator she would like to stay and have dinner. If the null hypothesis is that there is a predator, and the alternative is that there is not a predator, then which type of error would be preferable to make? Should she focus on minimizing her level of significance or maximizing her power in this test? Group of answer choices Type II is preferable, she should maximize power Type I is preferable, she should maximize power Type II is preferable, she should minimize significance Type I error is preferable, she should minimize significance

9.2 Let $G(s)$ be the transfer function for a linear system. Show that if we apply an input $u(t) = A \sin(\omega t)$, then the steady-state output is given by $y(t) = |G(i\omega)| A \sin(\omega t + \arg G(i\omega))$. (Hint: Start by showing that the real part of a complex number is a linear operation and then use this fact.)

Texts: An NMOS differential amplifier is built with two matched transistors, having gm = 4 mA/V, Vt = 1V; VDD = Vss = 15V; RD = 10kΩ Constant current source I = 2mA has an internal resistance RSS = 200kΩ Suppose that the differential input Vid = 20.sinwt (mV) is applied to Q1 and the output is taken single-endedly from Q1, such that Vo = Vd1 and the output is applied to a load RL = 10kΩ. a) [10] Draw the circuit. Check if the MOSFETs are in the active region. b) [15] Comment on the performance of the circuit. c) [10] Calculate the minimum VSS value to obtain the same performance with a single RSS = 100kΩ and comment on the result. d) [5] Calculate and sketch the input and the total output voltages (DC+AC).
