Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achieve this reduced power dissipation, and explain how you could use an ideal transformer to supply this reduced voltage to the heater.
the following binary numbers are all represented using 6 bit signed 2's complement. all addition should also be conducted in 2's complement form. A=111000; B=010110 (a) what is A's value in decimal
Compute the first 10 samples of the step response for the nonrecursive difference equation: y(n) = x(n) -0.5x[n-1]-0.7x[n-2] Indentify which of the following filters are recursive and which are nonrecursive.
A byte containing 01100011 is right shifted (right-most bit first) into an 8-bit shift register with an initial state of 00110110 (01100011=>00110110) What does the shift register contain after three clock pulses
Determine the maximum and minimum spectral frequencies received from a stationary GSM transmitter that has a center frequency of exactly 1950.000000 MHzassuming that the receiver is traveling at speeds of.
design a 4th order Butterworth band-pass filter, using a low-pass filter followed by a high-pass filter, to extract the 1200Hz and 1500Hz components from the signal x(t) a. Determine the cut-off frequencies of the low-pass and the high-pass filters..
Suppose we have a causal LTI system with rational system function H(s). We don't know H(s), but we do have the following information: i. When the input to the system is x(t) = u(t), the output y(t) is absolutely integrable.
