Find Port 1 (P1.7-P1.0) of U8 in the 4096/4196 schematic. On a separate piece of paper, draw an 8-bit controlled inverter for that output port. The inverting function is to be controlled by the P3.5 output (pin 15).
Calculate the sag from the taller of the two supports which must be allowed so that the factor of safety shall be 5.
A carrier signal c(t) = 10 cos(2pifct) is modulated using a message signal m(t) cos(20pit). The modulation is FM, with kf = 50.Write equation for modulated signal What is average transmitted power & modulation index
How should the output of an oil furnace ignition transformer be tested?
Determine the transfer function for a second order band pass filter with specifications. Chebyschev type with 1 db ripple in the pass band Lower cutoff frequency = 100 radians/sec Upper cutoff frequency = 169 radians/sec Pass band gain = 1
An input signal x(t) = cosωct is sampled by an ideal sampling function with ωs= 1.5 ωc. The sampled signal is then filtered with an ideal low pass filter H(ω)= rect(ω/1,5ωc) to form an output signal y(t) a. Sketch the fourier transform of the sampl..
At a certain location, the horizontal component of the earth's magnetic field is 3.70 10-5 T, due north. A proton moves eastward with just the right speed for the magnetic force on it to balance its weight. Find the speed of the proton.
(a) Using superposition, determine the voltage labeled vx in the circuit represented. (b) To what value should the 2 A source be changed to reduce vx by 10% (c) Verify your answers by performing three dc sweeps in PSpice.
the ends of a length of wire are labeleda and b. if the current in the wire is iab -3a are electrons moving toward
For any lossless reciprocal three-port network, one port (say port 3) can be terminated in a reactance so that the other two ports (say ports 1 and 2) are decoupled (no power flow from port 1 to port 2, or from port 2 to port 1).
A semiconductor has Nc=10^19 cm^-3, Nv=5x10^18 cm^-3 and Eg=2eV. If it is doped with 2x10^17 acceptors (fully ionized), calculate the electron, hole and intrinsic carrier concentrations at 627 C. Sketch the simplified band diagram, showing the pos..
A transformer core with an effective mean path length of 10 in has a 300-turn coil wrapped around one leg. Its cross-sectional area is 0.25 in2, and its magnetization curve is shown in Figure 1-10c. If current of 0.25 A is flowing in the coil, wha..
Design a circuit to supply a -2.5 reference voltage as the input to a voltage follower if only 9 V batteries are available. Use an In4740 diode, which has a Zener voltage of 10 v at a current of 25 mA.
