In an FM transmitter, the output is changing between 90.001 and 89.999 MHz 1800 times a second. The information signal amplitude is 1.5 V. Determine the carrier frequency and information signal frequency. If the output deviation changes to between 90.002 and 89.998 MHz, calculate the information signal amplitude.
Light is incident from air to glass at Brewster's angle. Determine the incident and transmitted angles. Glass has refractive index n2=1.45.
Include the unused states in the design, arranging the circuit to switch from any unused state to the 'main sequence' within one clock cycle, and show the state diagram that applies here. Clearly show all the steps of the design procedure used.
What effect do internal capacitances in the transistor model have on practical performance of a real system? How would you use these model values to predict system performance?
Is it possible to produce a large size dynamo which can satisfy the electricity needs of a home. Is is possible to use the electricity produced by the dynamo to run a motor which can operate dynamo.
Compute and plot the correlation sequences r s1s2 (l), r s0s0 (l), r s1s0 (l) and r s2s0 (l) . Compute and plot the cross-correlation sequences and of the received signal with the template signals and s 2 (n).
