In a line of sight link , the transmitted power = 1 watt at the frequency of 11 GHz and the transmitting antenna has gain of 1000 , the receiving antenna is 40 Km apart from the transmitting station, find the receiving antenna gain in order to secure a C/N of 30 dB given that the noise power level N=-125.6 dBW , you need to account for a 2 dB cable loss on the receiving side.
Current, voltage, and power to a three phase system are measured and found to be 20 A, 550 V and 10.5kW respectively. Determine equivalent circuits per phase as follows: (a)wye connected series combination of resistance and reactance in each phase.
A linear circuit has a capacitance of 1.0 mF and an inductor of 1.0 µH. If the frequency response of the voltage gain should stay the same and the capacitor is scaled to 70 µF, what should the value of the inductor be
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]
desgin a four-bit combinational circuit 2's complenmter.(the output generate complement of the input binary). then construct truth table for the input and correspondinf output. use kmap to find each outpt in terms of of inputs.
Consider an RLC circuit with R = 5 Ohms, L= ½ H, C= 2/9 F and input voltage e(t) = exp(-t/2)a. Starting from KVL show that the DE for the voltage across R is given by: v'' + 10 v' + 9 v = -5 exp(-0.5 t) b. Find vc in terms of the arbitrary constants ..
Data Transfer/Manipulation Instructions a) If accA holds $16 and accB holds $2A, what memory locations will change value after executing the STD $637F instruction. Identify the new value in any changed memory locations.
When the input x(t) = 5u(t) is applied to a linear second-order circuit the response of the state variable is y(t) = 10e^(-100t)-5e^(-200t) + 5. Design a simple RLC circuit that would produce all of these responses.
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
The sampling frequency in a DSP system is fs=16 kHz. Anti-aliasing filter used in the system is the second-order Butterworth filter with cutoff frequency of fc=4.2 kHz. What is the percentage of aliasing level at the cutoff frequency
From a large lot of new tires, n tires are to be sampled by a potential buyer, and the number of defectives X is to be observed. If at least one defective is observed in the sample of n tires, the entire lot is to be rejected by the potential buye..
Problems for the basic concepts of Induction motor(IM) taking care of slip and syncronous speed and motor speed and its relationship, A 50 Hz induction motor operates in such a way that the slip is 1.45.
Consider a 1.5 MVA, 4.16 kV, 3φ. 60 Hz synchronous generator. When operating at full load and rated voltage at a power factor of 0.9 lag, WHAT is the stator current in phase b[magnitude & angle]
