"Power Outage" refers to that the receive signal power falls below a certain threshold. Consider for a RF signal in a Rayleigh fading channel with average receive signal power 2?2 = - 80dBm. What will be the power outage probability of this channel relative to the following threshold (P0):a) -95dBm.b) -90dBm.c) if the power outage probability of 0.01 for the threshold P0 = -80dBm, For Rayleigh fading , what value of the average signal power is required ?
Saw on internet some equations to convert from frequency in hertz to mph. Some equations need a gear ratio while others do not. I found the equation mph = circumference * RPM * 60.
The total charge that has accumulated on the positive plate of a capacitor varies with time. The charge follows q=At^2 for the first 4s. a) Find the value of current at t=2,6,9,12,16 s. b) Sketch the current i(t) as a function of time
Finding the periodicity in N of the discrete time signal x(n) = Cos(3pi*Ts.n + pi/4) and then plotting the discrete signal. From this the condition on the sampling period is determined
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
Drift velocity the actual (physical) velocity of electrons along the wire. Transmission velocity the rate at which information can be transmitted electronically using conducing wires. How is it possible that the transmission velocity is so much faste..
Design a 16 bit x 16 bit combinatorial multiplier. Use a topology similar to the 4x4 multiplier.
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s. What is the indicated temperature at these tim..
Transmit this data wirelessly to a base station for storage. How much bandwidth would you need.
Memory storage and bit density, A hard disk contains four Platters. Each side of the platter is coated with a magnetic oxide, allowing data to be stored on it. The platters are 3.5 inches in diameter.
Design a bandpass filter of 'Sallen and Key' topology and having the following characteristics fo = 3.3 kHz, Q = 2.2
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
