A transmitter with power output .75 watts operates at 1090 MHz. The transmit antenna gain is 2.1dB, and the receive antenna gain is 1.6dB. The received is 18Km away from the transmitter. The receiver has a Noise Figure of 8dB, Bandwidth 1.7 MHz and the Data Rate is 640K bps. You may assume T0 = 290K. Assuming no other noise sources or losses, calculate the received Eb/N in dB.
Calculate the following. a) What is the magnitude of the voltage in a wall socket if the effective voltage is 240 Vrms b) What is the magnitude of the current if the effective current is 360 mArms
A composite analog signal is given in the following expression: x(t)=1.2 sin(2pi60ft)+0.0001cos(2pi1ft) -If this signal was sampled at 1000 Hz, derive the expression for the sampled sequence x[n] with n being the sampling index.
our senior design team is designing a force sensor to measure a force signal and analyze the signal with a microcomputer (binary system). The analog force signal is between 10 N and 70 N and has the frequency bandwidth of DC - 1000 Hz.
Write an arduino code that reads the temperature from a thermistor. This code must read a set temperature from the serial monitor and if the temperature from the thermistor is higher than the set temperature then a fan and led will turn on.
Electricity is distributed from electrical substations to neighborhoods at 15,000 Volts, to a transformer on utility poles near homes, where is it stepped down to 120 Volts for household use.
(1) What might be an example of an input and an output What are some simple examples of what constitutes the distinction between input into a program and output from the program (2) What type of arithmetic operations are supported in C++
figure out how to plot the response of a system given an input. transfer function for the system is: H(s) = 1000/(s^2 + 110s + 1000) input is periodic, and represented by: u(t) - u(t-pi/2)
During the k^th sampling interval of a CVSD modulation scheme, the current value of input x(k) is 1000, the previous value of approximating staircase function x f(k-1) is 990, and the current value of ä(k-1) is 30
A certain pn junction is operating with Vt=26mV and ni=1.08x10^10 electrons/cm^3. The doping concentrations are Na=2x10^15 cm^-3 and Nd=9x10^16cm^-3. The diffusion coefficient are Dn=34cm^2/s and Dp=12cm^2/s.
Determine the initial stored charge. Determine energy of the capacitor. If this capacitor is discharged to 0 V in a time interval of 1 s, find the average power delivered by the capacitor during the discharge interval.
Write a 68000 assembly program to subtract two strings of A15 ASCII characters. The first string is stored starting at $502030. The second string is stored at location $302510. The ASCII character in location $502030 of string 1
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
