Similar to my last question. I broke these into multiple parts but tried to keep all of the information together. Why was this portion not acceptable on question_id=7502055?
It is decided to apply a Fast Hopping (FH) scheme on the above ASK system. The hopping is made over 12 channels of 100 kHz; or over 1.2 MHz bandwidth. The ASK signal hops 6 bands per bit period. Now a strong jammer randomly jams one of the 12 FH c..
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
The steady state solution of stable systems is due to simple poles in the jO axis of the s-plane coming from the input. Suppose the transfer function of the system is: H_ (s)= (Y(s))/(X(s)) = 1/([(s+1)^2]+4))
An earth station receive antenna has a sky component temperature of20 K, a ground component temperature of 15 K . What is the total antenna noise temperature [K]
A 50HP single phase motor operates from a 480V, 60HZ supply. When delivering full rated power the motor efficiency is 89% and the power factor is 0.78 lagging. Determine the full load current.(Hint: 746W=1HP)
Assuming that the door is relatively thin, the moment of inertia will be the same as that of a rod rotating about an axis at its end. If the mass of the door is 10 kg and its width is 1.5 m, find the angular acceleration of the door after applying..
A long cylindrical wire has a radius equal to 2 cm and carries a current of 80 A uniformly distruibuted over its cross-sectional area. Find the magnetic energy per unit length within the wire.
A boost converter has 5 V input and 12 V output at 60 W. The diode is ideal. The transistor requires 1 uS to turn on or off. The switching frequency is 100 kHz. The storage components are large.
A pnp power transistor operates with an emitter-to-collector voltage of 5V, an emitter current of 10A, and VEB = 0.85V. For ß = 15, a) What base current is required b) What is the IS for this transistor
Use two different criteria for determining the effective bandwidth of e^(-t)u(t). Ad the bandwidth, use the frequency at which the amplitude response drops to 1% of its peak value (at w=0). Next use the 99% energy criterion for determine the band ..
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
A rod of ultrahigh purity copper is 1 cm in diameter and 10 cm long at room temperature. Its mass is found to be 70.18 g. Determine the inter-atomic distance between two nearest- neighbor copper atoms.
