In the CMOS circuit shown, electron and hole mobilities are equal, and M1 and M2 are equally sized. The device M1 is in the linear region if
- A binary symmetric channel (BSC) has a transition probability of 1/8. If the binary transmit symbol X is such that P(X=0) = 9/10, then the probability of error for an optimum receiver will be
-
The signal m(t) as shown is applied both to a phase modulator (with kp as the phase constant) and a frequency modulator (with kf as the frequency constant) having the same carrier frequency. The ratio kp/kf (in rad/Hz) for the same maximum phase deviation is

With 10 V dc connected at port A in the linear nonreciprocal two-port network shown below, the following were observed: (i) 1 Ω connected at port B draws a current of 3 A(ii) 2.5 Ω connected at port B draws a current of 2 AFor the same network, with 6 V dc connected at port A, 1 Ω connected at port B draws 7/3 A. If 8 V dc is connected to port A, the open circuit voltage at port B is
