a circuit with a resistor is connected to a DC supply and a Current of 2A and producing a heat. What is the rms Voltage that must be applied by a AC supply to produce 3 times this heat if all other conditions remain the same?
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
Create a circuit of three level-sensitive D latches connected in series. Use a timing diagram to show how a clock with a long high time can cause the value at the input of the first D latch to trickle through more than one latch during same clock ..
Using the Quine-McCluskey's method, find the SOP and POS solutions for the function below, and verify that they match with the Karnaugh map solutions. f (a,b, c, d) = \(\sum m(0,1,6,15)+ \sum d(3,5,7,11,14)\)
