A USB communication link requires a circuit that produces the sequence 00000001. You are to design a synchronous sequential circuit that recognizes this sequence. Additionally, there is an E input to this circuit.
A 40-hp, 500 V, 1200-rpm DC shunt motor has rotationallosses of 2000 W at rated speed. The armature resistance is 0.46Ω and the field resistance is300Ω. A) Calculate the armature current when the motor is delivering rated load at rated voltage and..
A spread spectrum system has a code rate that can be switched from 500 kbps to 1.5 Mbps in 100 k steps. If the message rate is 1.3 kbps and the processing gain is 1050. What step should the code be set to
A certain power amplifier with crossover distortion has the input/output voltage relationship vo (t) = vi (t)3 (2.39) a) Use example voltage values to show that this does not satisfy the relationship. b) Let vi (t) = sin (pi t) .
What is the equivalent admittance of the circuit for Z1 = 12, Z2 = 5 - j7, Z3 = 4 + j36 and Z4 = j10 (all in ohms) Note: Z1 and Z3 are in parallel connected to Z2 + Z4 in series, equal Zt || to Z1||Z3
Write down the principle of energy conversion and give an example for single and double excited system.
four loads are connected in series across 110 volts D.C.THE loads fail to operate.a voltmeter connected in succession across each device reads 0 across the first three loads and 110 volts across the fourth load.What circuit fault is indicated at t..
Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150(that is, $95 parts
A CG amplifier is specified to have Cgs=2pF, Cgd=0.1 pF, CL=2 pF, gm=4 mA/V, Rsig = 1k-ohm, and R'L = 20 k-ohm. Neglecting the effects of ro, find the low-frequency gain vo/vsig, the frequencies of the poles fP1 and fP2
A certain lightbulb has a tungsten filament with a resistance of 21.9 when at 20.0°C and 145 when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here.
A 100uf capacitor is initially charged to 100V. We want 90% of the initial energy to remain after 1 minuet. What is the the limit on the leakage resistance for the capacitor
Given a voltage of 100 volts with a phase angle of 0 degrees, applied across an impedance of 50 ohms at an angle of +30 degrees. This is an inductive impedance - not TOTALLY inductive, but more inductive than capacitive.
