design a circuit for a light fixture controlled by four switches,where flipping one of the switches turns the light on when it isoff and off when it is on. give expression and show using logic gates.
The electric motor in a street car develops a power output of80 hp at 1200 rpm as the vehicle moves up a hill at a speed of 30mph. Assume the gearing losses are negligible, calculate: (a) The torque developed by the motor.
Two identical CS amplifiers are connected is cascade. First stage is fed with a source Vsig having a resistance Rsig = 100k Ohm. A load resistance Rl = 10k Ohm is connected to the drain of the second stage.
An LED is connected to a 74LS244 in an active-LOW configuration. The key parameters for the 74Ls244 are IOH=-15 mA, IOL=20 mA, VOH =2.0V and Vol=0.5V. The LED has a voltage drop of 2.0V and an operating current of 15 mA.
What is the reliability, the equivalent MTBF value, and the equivalent failure rate for a system that has a primary microprocessor circuit board and a secondary microprocessor circuit board that is hooked up in standby redundancy
Consider the convolutional code described by connection polynomials
how much work is done(by a battery,generator,or some other source of potenial difference) in moving Avogadro's number of electrons from an initial point where the electric potenial is 9.00V to a point where the electric potenial is -5.00V
A single - phase bridge rectifier is supplied from a 120 - V, 60 - Hz source. The load resistance is R = 200 ohm. a ) Design a C - filter so that the ripple factor of the output voltage is less than 5%.
The available powersupply voltages are VCC = 15 V andVEE=-15 V. Maximize |Avs| in a manner consistent with the otherspecifications. Use SPICE to find the midband gain and the upperhalf-power frequency for your design.
The average voltage across the load when the triggering angle is 140 degrees. Keep in mind that the conduction is incomplete when the triggering angle is greater than 140 degrees.
assuming XTAL=11.0592 MHz,write a program to genrate a square wave of 20 Hz frequency on pin2.3?
a sound distribution system has the following outputs 10 watts at 8ohms,5watts at 4 ohms, 15 watts at 16 ohms and 2 watts at 4 ohms if the input to the amplifier is 20 millivolts at 600 ohms how much gain in decibels will be required of the amplif..
