Two watt-meters connected to read the total power drawn by a balanced three-phase load. If the two readings are 1000 W and -1000 W, what is the total power drawn by the load?
A single-phase half-wave rectifier is fed with a triangular signal with period 2 . The maximum positive and negative amplitudes are ± 12 V rms. determine: a) The value of the DC output voltage. b) The percentage of curly
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
Write an instruction sequence to set bits 3, 2, 1, and 0 of memory location at $1000 to 1 and leave the upper four bits of the same locations unchanged. use hcs12/9s12 to program.
What is the relation between the conductance and the capacitance of two parallel conductors immersed in a lossy dielectric medium that has permittivity and conductivity?
A four-pole armature is to generate an average e.m.f. of 2.0V per conducter, the flux per pole being 25mWb. Calculate the speed, in r/min, at which the armature must rotate.
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal) and should have a stability margin of 92%.
The highest frequency contained in a certain analog signal is 4 kHz. Determine the sampling rate if it is chosen to be 50% greater than the theoretical minimum.
Discuss briefly the implications of these values of T1 for ultrasonic imaging. Repeat the calculations above with the angle of incidence of the ultrasound beam now being 60 degrees.
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 100 , inductive reactance XL = 100 , and capacitive reactance XC = 200 . All three components are connected in parallel to the source. what is The source current.
The Signal power to noise power ratio is an important measure of the transmission quality of any channel. If at the receiver there is a 12 dB signal to noise ratio and the received signal power is 50 micro W then calculate the received noise power..
a. Sketch the spectrum of the sampled signal up to 20 KHz. b. Sketch the recovered analog signal if an ideal (brick wall) low pass filter with a cutoff frequency of 4 KHz is used to filter the sampled signal in order to recover the orig..
The transfer function of a circuit is given by H(s)= 2s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator.
