Develop a series 90-30 program that functions a motor forward/reverse controller.. Design your circuit so that the stop push button must be pressed before the motor can switch direction. Also incorporate a 5 second delay to inhibit restart after the stop push button has been pressed. Green light should be on when motor is running forward and the white light should be flashing when in .
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
A 3-bit " comparator" circuit receives two 3-bit numbers, P = P2P1P0 and Q=Q2Q1Q0. Design a minimal sum-of-products circuit that produces a 1 output if and only if P
The basic sampling rate for the compact disc (CD) recording industry has been set at 44.1 kHz. (a) Determine the highest frequency of the analog signal that could theoretically be reconstructed from this sampling rate.
Discuss different applications that could use non-inverting and inverting amplifier circuits. Will the actual op amp characteristics cause any challenges if used for each application
pick two specific energy assets such as a specific power plant natural gas processing plant oil tanker oil production
a transmitters last stage output impedance is 50 ohms. the transmitters antennas input impedance is between 30-j50
An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt). a) Find the power of the modulated signal. b) Find the frequency deviation Δf. c) Find the phase deviation Δφ.
If the voltage across a capacitor is a square wave, predict the resulting current waveform (draw the voltage and current waveforms). Repeat the process when the voltage across the capacitor is a sine wave.
A separately excited DC motor fed through asingle phase semi- converter runs at a speed of 1200 rpm when Acsupply voltage is 230V, 50 Hzs and the motor counter emf is 140v.The firing angle delay is 50 degree .
if we have a signal source impedance that is almost as high as the input impedance of the inverting Op Amp (Rin) what effect would that have. How much signal would appear at the inverting input of the Op Amp.
A current source, Is =16.5cos(2300t) A, a resistor R=134Ω, and an inductor, L=0.12H are all in parallel. Assume steady-state conditions exist. At t=3.9ms, find the power being absorbed by the a.)resistor, b.)inductor, c.) sinsuoidal source
Cellular membranes create voltage potentials by seperating thecharged ions. A membrane with 70 mV potential has 1 x 10^4 Na+ ionsflowing through it. Assuming the potential is constant, what is thechange of electrical potential energy experienced b..
