A two-port network is driven at both ports such that the port voltages and currents have the following values (Z0 = 50 Ω)
Determine the input impedance seen at each port, and find the incident and reflected voltages at each port
Given the excitations x[n] and the impulse responses h[n], find closed form expressions for and graph the system responses y[n] x[n] = u[n], h[n]=(4/7)δ[n]-(-3/4)nu[n]
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
where vsat is a relatively constant velocity. Determine the trans-conductance of such a device.
Design the instruction decoder using AND, OR, and inverter gates todecode the 3-bit op codes (bits D7, D6, D5, of 8-bit instruction)and produce the ADD, SUB, IN, OUT, and MOV control signals (thecontrol signal will be "1" when i asserts)
[Hint: As you should explain, this is equivalent to showing that the sum of two forward light-like vectors is forward time-like, unless the spatial parts are parallel.]
A pn-junction is formed in silicon by doping one side with acceptor atoms at concentration Na = 10^19 cm^(-3) and another side with donor atoms at Nd = 10^18 cm^(-3). What is the dopant concentration on the p-type side and on the n-type side
What is the primary purpose of a window function? For a 7-term moving average filter, what effect do the poles have on the frequency magnitude response and why?
A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 uH. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0
consider a signal xt 10 cos2pifct 4 cos 2pifmt. assume frequency modulation. the message frequency fm 23 khz.
A 23-kVA, 2300/230-V, 60-Hz, step-down transformer has the following resistance and leakage-reactance values: R1 = 4 ohm, R2 = 0.04 ohm, Xl = 12 ohm, and X2 = 0.12 ohm. The transformer is operating at 75% of its rated load.
generated by a loud speaker is reflected at two different walls with reflection coefficients r1 and r2. the signal x(t) recorded by amicrophone close to the loud speaker, after sampling is
What are advantages and disadvantages of using digital circuits in lieu of analog circuits to measure different parameters in mechanical systems
