Provide two designs of shunt regulators utilizing the 1N5235 zener diode, which is specified as follows: V(z) = 6.8V and r(z) = 5ohms for I(z) = 0.25mA (nearer the knee), r(z) = 750 ohms. For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current from the raw supply is limited, and therefore you are forced to operate the diode at 0.25mA. For the purpose of these initial designs, assume no load. For each design find the value of R and the line regulation.
Determine the expression for the frequency response H(Omega) of a causal IIR LTI discrete-time system characterized by the input-output relation. where |a|
Consider a series RLC circuit disconnected from a source at t=0. The circuit components are R=3 ohms, C = 500 F, and L = 1 H. We assume that Vc(0-) = 20 V and i(0-) = -0A. a) Find the natural reponse i(t) for t > 0.
Calculate the raial ion transport flux n_i*v_i_r in a cylindrical hydrogen plasma which has an axial curent of 1MA unifmorly distributed over a plasma of radius a = 1 m, has a uniform temperature of Ti = Te = 2 keV, and has an axial magnetic field..
Design of sync counter 0010 to 1101 using JK flip flops, Design a synchronous counter using J-K flip-flops that will count from 0010 to 1101 repetitively.
A certain 11 V dry-cell battery, completely discharged, requires a current of 100 mA for 1.2 hr to completely recharge. What is the energy storage capacity of the battery, assuming the voltage does not depend on its charge status?
Calculate The Average voltage generated in 6 turn full pitch coil of a 25 cycle alternator if the flux per pole is 7.2 x 10^5 maxwells. What is the effective voltage if the waveform is sinusoidal.
Draw circuit that implements parallel bit-slice parity checker. Its input is X=xn-1xn-2...x1x0 and it should produce output F=1 iff input X has even parity. Make sure to label all signals and ports.
Calculate the PMOS device with to acheive symmetric propagation delays in an inverter (tPLH = tPHL). Use Wn=450nm Ln =300nm and Lp=300nm and solve for Wp. So I think by some ratio I can find what Wp should be, maybe something like Wn/Ln=Wn/Lp
The configuration is shown in Figure 6.5. Use six LEDs as shown in Table 6.1 to represent the outputs. The Time in This State can be met in several ways. One method is to use a debounced switch as input, another to input a 1 Hz clock.
Consider a SISO link with received signal α = hs + n, where h is a zero-mean complex Gaussian random varaible with unit variance, where the power of the data signal s is mathbbE (IsI2) = P, and where n is a zero-mean AWGN scalar with unit variance..
The power transfer in a transmission line is governed by the equation P = VS * VR * sin\(\delta\)/X line. Basedon this equation what is the maximum power transfer that can be achieved, and what is its value if VS =VR = 1.0p.u
