a) what is the advantage of using a CPU register for temporarydata storage over using a memory location?b) If the stack segment register contains 3000H and the stackpointer register contains 8434H, what is the physical address of the top of the stack?
Consider a digital filter with frequency response: H(f)=11+f Assuming the sampling frequency is 1500Hz what is the frequency attenuation of a signal passing through this filter at 280Hz
Using data from the data sheets of the MAX505 DAC, and the various temperature coefficient of DAC errors specified at 25 degrees Centigrade, calculate the total Worst Case Error for a temperature deviation of 45 degrees Centigrade.
1. Find the change in currents due to change of voltage by (a) 5mv,(b) -10mv, (c) 15mv using small signal model and exponential modelof diode with n= 1 and biased at 2mA. 2. A step up transformer has the turn ratio of 2:5
An ADSL signal uses 250 channels, each of 4 kHz bandwidth. Assume the maximum signaling rate to be 1 symbol/Hz. QAM is used within each channel with up to 64 point constellations. What is the bit rate/channel
Three of the above single phase transformers are connected as a 3-phase transformer bank. The high voltage side of the transformer bank is connected in Y and the power is supplied to the transformer bank through a transmission line
(c) Use a single 4-to-1 multiplexer with an active low enable and an active high output and a minimum of additional gates. Show the function expansion both algebraically and on a Karnaugh map.
