a) Consider an n-p-n transistor whose base emitted drop is0.76 at a collector current of 10mA, What current will it conductat Vbe=0.70V? What is the base emitted voltage for ic=10microampere?b)A CE amplifier uses a BJT with B=100, Va=50V, biased atIc=0.5mA;it has collector resistance Rc=10Komi- Find Rin, Ro & Avoii-if Rsig = 10 Kom, and a load RL= 10 Kom. Is connected,find Av & Gviii- If Vπ is to be limited to 5mv, what voltage appears across & the load V0? What is the corresponding Vsig?

Consider two identical and redundant CFR (Constant Failure Rate) components having a guaranteed life of 2 months and a failure rate of 0.15 failures per year. What is the system reliability for 10,000 hours of continuous operation
A transmission line operating at 125 MHz has Zo = 40 Ω, α = 0.02 (Np/rn), and ß = 0.75 rad/m. Find the line parameters R', L', C', and G'.
A continuous-time signal x(t)=tri((t-1)/2) is sampled at three rates: 10, 2, and 1 Hz. Sketch the resulting sampled signals. Because x(t) is timelimited, its bandwidth is infinite. However, most of its energy is concentrated in a small band.
A continuous time system is described by y(t) = t tan(x(t)). The continuous time system is sampled every T seconds to obtain a discrete time system y[n]. determine the mathematical expression for y[n].
Design a second-order band-pass IIR filter with center frequency of 200 Hz when the sampling frequency is 1000 Hz. In order to ensure the filter stability set the poles at 0.94 radial distant from the origin
