A rectangular waveguide with dimensions a=2b=5cm operates at11 GHz. Assuming that the guide is filled with air, find the highest possible operating mode and the intrinsic wave impedance at that mode.
Calculate the unit step response of the DT systems with the following impulse responses: a-) h[k]= u[k+6]- u[k-10] b-) h[k]= 3^k- u[-k]
The minimum stopping distance for a car traveling at a speed of 30m/sand is 60 m including the distance traveled during the driver's reaction time of 0.53 s. What is the minimum stopping distance for the same car traveling
The 24-bit data field of a packet is given by 0xBC603F. The packet contains a CRC with the generator polynomial given by X 3+X+1 a) Find the CRC checksum. Provide the complete code-word including the checksum in hex.
A 35 kVA transformer supplies a load of 12 kW at a power factor of 0.45 lagging. Find the percentage of full load the transformer is carrying. If additional unity power factor loads are to be served with the same transformer,
The single phase for equivalent circuit parameters for the windings of the motor referred to the stator in (ohms/phase) R1=0.2 R2=0.2 X1=0.3 X2=0.3 .the core losses and the magnetization can be ignored.
three single-phase transformers rated at 250kVa, 7200V/600, 50Hz, are connected in wye-delta on a 12470V, 3 phase line, if the load is 450kVA, calculate the current in the incoming and outgoing transmission lines and in the primary and secondary w..
A DC motor is driving a load given by TL = 2 + 0.02ωL Nm , where ωL is the speed in rad/sec. The armature resistance of the motor, Ra = 2Ω . The machine constants, kE=kT =0.4 (in SI units).
If I want to stream audio data over a digital data link how much channel capacity is required for stereo 16 bit audio sampled at 44kHz. How does this rate compare to common rates for MP3 formatted audio files.
Deduce the equation of the total transference for a feedback system with an operator of gain a, and a feedback network of transfer β.
If a patient is on a drip with a drip rate of f(t) = 150e^0.0167t mL/hr, calculate the amount of substance transferred into the patient over a time period of 10 hours, use time intervals of 1 hour. Compare
Consider the following function of t, f(t)=1/a[u(t-T0)-u(t-T0-a)]. Here both T0 and a are positive numbers. If you pick some value for T0 and a you discover that you have a rectangular pulse starting at T0 having width a and height 1/a.
