Power Dissipation Problems
A signal generator outputs a sine wave signal with a frequency of 1000 Hz and an rms voltage of 20.0 V. The output of the spectrum analyzer is connected to a 200 ohm resistor.
a. What is the power dissipated in the 200 ohm resistor in watts, in dBW, and in dBm?
b. An amplifier with a gain of 15 dB over the frequency range 0 Hz to 10 kHz is placed in the circuit between the signal generator and the resistor. What is the power dissipated in the 200 ohm resistor in watts and dBW now?
c. An attenuator with a fixed attenuation of 6.0 dB over the frequency range 0 Hz to 10 kHz is placed in the circuit between the amplifier and the resistor. What is the power dissipated in the 200 ohm resistor in watts and dBW now?
d. The attenuator in part (c) above is replaced by a low pass filter. The filter has an attenuation of 3.0 dB at 500 Hz and an attenuation above 500 Hz of 12 dB per octave. What is the power dissipated in the 200 ohm resistor in dBm now?
very useful not only in obtaining the rectangular and polar forms of complex numbers
You want to download a 5 Mbit file over a 10-Mbps Rayleigh fading channel in the 1800 MHz frequency band. You are traveling at 6 km/h and use 1000-bit packets.
Draw the per-phase impedance diagram of the power system and Draw the impedance diagram in per-unit system
Step-down transformer
Finding values of a composite discrete time signal, A discrete time signal x(n) = x(n-1) + x(n-3) with initial conditions x(0) = 0, x(1) = 1 and x(2) = 2 is examined and the first 51
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
Maximum Amount of Channels A Link Can Carry, A microwave radio link operates over a bandwidth of 400 MHz at C band. The link carries a number of channels of data using FDMA.
Comparing Error probabilities with BPSK and QPSK systems, A BPSK system and a QPSK system are designed to transmit at equal rates; that is, two bits are transmitted with the BPSK system
Derive the dynamic model and average value circuit of a buck converter assuming the ESRs of the inductor and capacitor are not equal to zero.
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
What is the attenuation per octave between 1 kHz and 10 kHz? What is the increase in attenuation between 5 kHz and 10 kHz?
First you must give all different possible connection types for them and then, for each case, you should develop some tests that can define the connection type and calculate the current passing through the capacitors.
