a certain ideal voltage generator is characterized as v(t) = 40 sin 377 t . If this generator is measured with a DC voltmeter, the instrument reads 12 volts, what is the rms value of this voltage waveform
Design a first-order RC high-pass filter for the given cut-off frequency of fC = 2400 Hz and the capacitor value of C = 47 nF. What is the required resistor value
A PWM is used in 8-bit mode to produce a signal with a 1 msec period and 60% duty cycle. Determine the value required for any pre-scaling, and the values for the period, and duty cycle registers. The E-clock is 24 MHz.
Let x1[n] = {-2,1,-3,-5,6,8} with arrow under -2 and x2[n]={1,2,3,4} with arrow under 1. a) determine circular convolution of 7 between x1[n] and x2[n] b) verify (a) calculations by computing the DFTs and IDFT.
On a spacecraft two engines fire for a time of 541 s. One gives the craft an acceleration in the x direction of ax = 4.90 m/s2, while the other produces an acceleration in the y direction of ay = 7.60 m/s2.
pecify the value for R. What is the diode current with the load connected What is the increase resulting in the output votage when the load is disconnected What change results if the load resistance is reduced to 100ohms? To 75ohms To 50ohms
Efficiency in a power transformer is 98.6% when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
A calibrated RTD with ALPHA = 0.0041/°C, R = 306.5 Ohms at 20°C, and PD = 30 mW/°C will be used to measure a critical reaction temperature. Temperature must be measured between 50° and 100°C with a resolution of at least 0.1°C.
A three phase load draws 100kW at a poer factor of 0.7 laggaing from a 220V line to line. In parallel with this load is a three phase capacitor bank which draws 60kVAR. Find the total line current and the resultant power factor.
Two infinite, thin wires are oriented in the x-direction. One is at the origin, carrying a current of 1A. The second wire is at (0,20cm,0) carrying a current I in the same direction. What current is needed in the second wire to produce 0 magnetic ..
Assume that you have two DC voltage sources of 1.5 volts each (like two AA batteries). The positive terminals are wired together (joined together) and the negative terminals are labeled A and B respectively.
Using D-type flip-flops, design a synchronous Moore finite-state machine that monitors two inputs A and B, and asserts a scalar output if the number of 1s observed on the inputs is a multiple of 4.
A 6-bit DAC has an input 1001012 and uses a 10.0-V reference.
