Assume that two antennas are half-wave dipoles and each has adirective gain of 3 db.If the transmitted power is 1 w and the twoantennas are separated by a distance of 10 km,what is the received power?Assume the antennas are alligned so that the directive gainnumbers are correct and that the frequency used is 100 MHZ.
A 0.51-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched length triples.
Your circuit has an input, controlled by a switch, that specifies which of the two names are displayed. For example, 0 displays JOsias and 1 displays KAbimb in Braille. A separate LED will be used to indicate the end of the sequence.
Discuss how you can identify which resistances are in series and which ones are in parallel in a series-parallel circuit. How might this affect how you measure current and voltages in the circuit with a digital multimeter.
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
The heavy-duty rechargeable battery you selected can provide a continuous 9A of current at 12 V for a 4-hour period of operation each night before being completely drained.
If 1000J of energy is required to move 9x10^19 electrons through alamp having a resistance of 25Ω. Find the current through the lamp and the voltage
The armature of a shunt generator as a 0.05 ohms resistance. Each brush has effective resistance of 0.02 ohms. The terminal voltage is 100V while the current is 40A. What is the efficiency of the generator
An 80 kHz sinusoidal voltage has zero phase angle and a maximum amplitude of 25 mV. When this voltage is applied across the terminals of a capacitor, the resulting steady state - state current has a maximum amplitude of 628.32 microamps.
An emitter follower, when driven from a 10 kohm source, was found to have an output resistance Rout of 200 ohm. The output resistance increased to 300 ohm when the source resistance was increased to 20 kohm.
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 amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal = 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input (b) SNR at the output (c) Noise figure
Describe the relationship between peak voltage, peak-to-peak voltage and rms voltage. Include in the discussion which values can be demonstrated with the laboratory test equipment.
