convert the decimal +46 and +29 to binary, using thesigned-2's-compliment representation and enough digits to accommodate the numbers. Then Perform the binary equivalent of (+29)+(-49), (-29)+(+49), (-29)+(-49). convert the answers back to decimal and verify that they are correct.
A three-phase 5 hp, 208 V motor has an efficiency of 92%, and a power factor of 0.87 (lagging) when it runs at full power. Calculate the motor phase currents and line currents if the motor is wye connected, and delta connected.
If an input signal with v(t) = 10 sin ( 2pi f 1592 t + 0º ) is applied to a series RL circuit with R = 1000-ohm and L = 0.1 H, what is the magnitude of the total circuit impedance
2. What is the sampling period 3. What is the bit time 4. What is the bit rate of that system 5. What is the time allotted to each channel
A 460-V, three-phase,60-Hz system supplies power to a 10-kVA, delta-connected resistor load; a 50-kVA, 0.86 power factor induction motor, and a wye-connected synchronous motor that is operating at 0.62 power factor leading
Consider the function f(x1,x2,x3,x4)= (x1 + x2 + ~x3 + x4)(~x1+ x4) a. Find the canonical POS of thefunction F using minterms. b. Derive the simplest POS expressionof F using algebraic manipulation.
You must design a three axis position indicator for the latest robot arm. Using no more than two operational amplifiers, design a circuit that uses three inputs, v1, v2, and v3 to produce an output signal vo=3 v1-2 v2-5 v3.
Design a full-adder using only a minimum number of 2x4 decoders. The complements of variables are not available but logic levels 1 and 0 are available.
A signal, m(t) which is bandlimited to 20 KHz, is going to be transmitted over a channel a) If the stepsize must be less than \(.002 m_{p}\) and the number of steps mut be a power of 2, calculate the minimum number of bits that satisfies this crit..
Model the line as an infinite filament of current under dc conditions. Calculate the magnetic field intensity in amperes/meter at the top of the head of a man who is 2 meters tall. Assume the man is standing on the ground directly underneath the l..
A load ZL is connected to the secondary of a linear transformer that is characterized by inductance's L1 = 1 H and L2 = 4 H and a unity coefficient of coupling. If w(omega) = 1000 rad/s, find the equivalent series network (R, L, and C values) seen..
Find the current that flows in a silicon bar of 10-µm length having a 5-µm x 4-µm cross section and having free electron and hole densities of 105 / cm³ and 1015 / cm³, respectively, when a 1 V is applied end-to-end. Use µn = 1200 cm²/V·s and µp =..
