Synchronized shift-register outputs Consider again the diagram of Figure E14.30(a), but suppose that now the output x comes from a circular shift register, whose rotating sequence is initialized with "1000". Suppose also that the sequence y must be delayed with respect to x by one clock period (so y should be initialized with "0001"). A (bad) solution analogous to that in Figure E14.30(b) could be employed, requiring two circular SRs. As in the exercise above, devise a better circuit that solves this problem.
a) Three delta-connected absorb 60 KW when connected to a 3 phase line. IF they are reconnected in wye, calculate the new power absorbed. b) Three 10uF capacitors are connected in wye across a 2300v, 60 Hz line.
All of us know that an automatic iron box set at "silk" will get heated upto a particular value, and if it is set at "wool"' iron box will get heated upto a higher value. Draw a block diagram representing the control system.
Design a full wave (Bridge) rectifier as a dc power supply that provides a peak dc output voltage of 15V on which maxiumum of 5% ripple is allowed. The rectifier feeds a load of 200Ω. The rectifier is fed from the line voltage (120V rms, 60 Hz) th..
Assume a 20 V voltage drop occurs across an element from terminal 2 to terminal 1 and that a current of 4A enters terminal 2. (1) Based on passive network convention, state whether the element is absorbing or delivering power.
if the equation for a mesh current is done and the current comes out negative, with the assumed clockwise direction. does that mean that the current is actually going in the opposite direction
The density of electrons and the electron mobility in the graphene sheet are NI = 5 x 10^12 cm-2 and µ0 = 20,000 cm2/Vs, respectively. a) Determine the sheet resistance of this graphene film.
Explain how the semiconductor behaves as n-type
A 1200-kg car moving at 20 km/h is accelerated at a constant rate of 4 m/s2 up to a speed of 75 km/h. What are the force and total time required?
A 150 MVA, 24 kV, 123% three-phase synchronous generator operates with an induced voltage that is twice the rated line-to-neutral voltage. Calculate the three-phase steady-state short-circuit current at the generator terminals.
A point source of light is 12 cm below the surface of a large body of water (n=1.33 for water). What is the radius of the largest circle on the water surface through which the light can emerge
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
In a feedback system, the forward path has a transfer function of the form G(s)=k/(1+s/Omega_p) and the feedback path has a gain of k_fb which is less than unity. Calculate the bandwidth of the closed-loop transfer function
