Consider the replacement of a DBS dish antenna with a microstrip array antenna. A micro strip array offers an aesthetically pleasing flat profile, but suffers from relatively high dissipative loss in its feed network, which leads to a high noise temperature. If the background noise temperature is TB = 50 K, with an antenna gain of 33.5 dB and a receiver LNB noise figure of 1.1 dB, find the overall G/T for the micro strip array antenna and the LNB if the array has a total loss of 2.5 dB. Assume the antenna is at a physical temperature of 290 K.
Sketch the output voltage of the circuit shown in Figure to scale versus time. Sometimes, an integrator circuit is used as a (approximate) pulse counter. Suppose that the output voltage is -10 V. How many input pulses have been applied?
A series circuit has a 1k(ohm) resistance and a 1k(ohm) inductive reactance. v1= 1 vrms a. what is the impedance of the circuit in rectangular form b. the frequency is given as 1kHz, what is the inductance of the coil L= c.
Write the VHDL architecture file for the Y(5) output only for a 8-to-1 demultiplexer. The inputs are D, the selects S0-S2, and the ouputs Y(0)-Y(7). the select lines are bit_vector types, the data is bit type and the outputs are bit_vector types.
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the initial state.
Derive an expression for evaluating the measurement error, ?Terr = Ttip - T8,i, which is the difference between the tip temperature, T lip , and the water temperature, T8.i'
How to find impendence in a series parallel circuit without using imaginary numbers. The circuit in question has a voltage source of 25 volts frequency is 100 Khz then the R1 resistor 220 ohms in series with an inductor
An LED is rated at VF = 1.6 Volts to 2.0 Volts at IF = 20 mA. What value of series resistance is needed to limit the LED current to 20 mA when this LED is connected to a 32 Volts peak source
Three single phase transformers are used to form a three-phase transformer bank rated 13.8kV (delta)/120kV (wye). One side of the transformer bank is connected to a 120kV transmission line
A 10-mV signal source having an internal resistance of 200 kO is connected to an amplifier for which the input resistance is 20 kO, the open-circuit voltage gain is 2000 V/V, and the output resistance is 1 kO. The amplifier is connected in turn to..
Can you do a survey paper on Wavelet and Subband Coding - I need 10 pages and I will provide the references.
Make a transfer function with numerator p(s) and denominator q(s)that will separate only the 3cos(4t) portion from the noise corrupted function: u(t) = sin(25t) + 3cos(4t) + n(t) wheren(t) is random noise. The degree of the polynomial on the denom..
A switch-tail counter uses the compliment of the serial output of a right-shift register as its serial input. (a) Starting from an initial state of 000, list the sequence of states after each shift until the register returns to 000.
