This washing machine would have a fill cycle to one level, a 10 second wash cycle, a 10 second rinse cycle and then drain. Include a start button, low level switch, high level switch, an agitator mo
A certain 12V dry-cell battery, completly discharged, requires a current of 100mA for 1 hour to completely recharge. What is the energy storage capacity of the battery (in kJ), assuming the voltage
design a PCM system that converts an analog signal to digital signal. specify the sampling frequency and the number of quantization levels you pick. the signal to quantization noise ratio must be hi
The armature of a simple DC generator is rotating at a speed of 188.5 rad/s. If the armature consists of 3 turns per coil, and a current is flowing in the field coils such that the field coils produ
Considering a three phase delta connected synchronous machine, the terminal line-line voltage is 1 p.u, the stator leakage inductance is 0.2 p.u, ignore the stator winding resistance, the rotor wind
The system receives three binary streams: A, B, and C. The system takes a look during each clock cycle at the last four bits of each stream (a(t), a(t-1), a(t-2), a(t-3)), (b(t), b(t-1), b(t-2), b(t
Design a network that accepts as input one unsigned 8-bit number (which refreshes every clock cycle and is never 0) and keeps a running sum until the sum exceeds 1000. The network outputs both the s
A desktop computer uses 60-250 W of power when active and 1-6 W of power when hibernating, depending on the model. An LCD monitor uses about 20-30 W of power, depending on the screen size.
The ac voltage that is supplied from a wall plug to the incandescent light is 170V sin[(377 rad/s)t]. If the current flowing through the light is 350 mA sin[(377 rad/s)t], determine the power that t
A baseband signal has frequencies from near dc to 4 kHz. Assume that the sampling rate is to be set at a value that will provide a guard band of 5 kHz for recovery. Determine the sampling rate (in k
A baseband signal has frequencies from near dc to 4 kHz. To ensure ease of recovery, the signal is to be sampled at a rate 25 percent greater than the theoretical minimum. Determine the time interva
draw a possible three phase motor that is based on two rotating electric fields and explain 1) the basic principle; 2) the drawback of the electric field based machine when it is compared to its cou
Two inductors with two separate cores are used in parallel in a circuit to share the current. A customer request a design improve by putting the two windings on to the same core. 1. Draw the two win
Design a 4-bit serial equality comparator. That is, if we have a3a2a1a0 = b3b2b1b0, then eq = 1. Note that a3a2a1a0 is stored at register 1, while b3b2b1b0 is stored at register 2. You have to imple
