Question about Matlab codes
Using the mfile window the height and distance traveled by a ball thrown at an angle A and with a speed v is: [h(t) =vtsin(A)-0.5gt^2] , [x(t)=vtcos(A)].Answer the following using v=10m/s and a time step of 0.001 and g=9.81m/s^2.
a) Use a loop, (now this book references using a for loop for one part and a while loop in the other part of this problem and do not know why), to calculate and plot the height versus ime for the angle A=35 degrees. Also, use the max function to find the maximm height reached and the time it takes to reach that height(the corresponding time instant).b) Polt on the same graph the trajectories (ie plot h versus x) corresponding to three different angles A=20 degrees, 45degrees,and 70 degrees.c) Using the angle A=30 degrees, plot the trajectories corresponding to three different velocities v=10,20,30m/s, on thre different graphs arranged vertically on the same page using subplot.
Evaluating Coding Gain, CNR, and BER of a DSSS-CDMA Transmitter, a. A DSSS-CDMA transmitter sends message signals at a rate of 5.0 kbps using a long chip sequence with a rate of 1 M chips per second. In the receiver, what is the processing gain (a..
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
The magnetic tape recorder uses linear analog to digital encoding. Telephone systems use non linear analog to digital conversion. Explain the difference.
Create a program using AsmIDE, which utilizes the Fox 11 68HC11 microcontroller board: Speech timer where max time is 5 minutes Use the switches for:
You have to figure out which one using cross or auto correlation.
Addition of two numbers in IEEE 754 format A) a=3f200000, b=be600000 B) a=3f200000, b=ff800000 C) a=01100000, b=80e00000
Measurements show that for a particular arrangement of the equipment and at a particular amplifier setting, the system will howl if 1% of the output power is fed back to the microphone. Estimate the power gain of the P.A. amplifier in decibels.
Modulating Radio Frequency Carriers to Carry Digital Data, Digital radio transmission requires the use of a carrier wave which is modulated by the digital data.
Methods used to eliminate noise from a spatio-temporal signal, Name and describe, in detail, 2 methods used to eliminate noise from a (spatio-temporal) signal. This question requires a clear, detailed explanation of the methods. Mathematical equation..
A certain cache has an access time of 2 nanoseconds and a hit percentage of 95%. If the main memory access time is 8 nanoseconds, what is the average access time for a read operation?
The purpose of this project is to design a device that would remotely control (from a Bluetooth-enabled mobile phone for instance) at least two actuators (e.g. relays and switches).
