Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, Resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the Resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the Resulting matrix The code requires nested Parallelism.

Some time during my development works I had the need of printing the contents of a ListView control. So I wrote down the code for a custom control, named PrintableListView, that solved the following two problems: * extend the print on multiple pages when the width of the list exceeds the width of the print page, * shrink, optionally, the list in a way that the Resulting width fits o

P3.18. An analog signal xa(t) = sin (100πt) is sampled using the following sampling intervals. In each case plot the spectrum of the Resulting discrete-time signal. Ts= 0.1 ms, Ts= 1 ms, Ts = 0.01 Sec

Run following Matlab commands to make sure the installation worked correctly. Unlike query function, filterdb does not load all waveforms to memory but returns filtered database object. This is useful when the Resulting set of the query is too big to fit in memory. Consequent calls to read function can be made to read content of this filtered database object.

Introduction ? ? The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs new Cortex family. With high performance and power efficiency, it targets a wide variety of mobile and consumer applications including mobile phones, set-top boxes, gaming consoles and automotive navigation/entertainment systems. The Cortex-A8 processor spans a range of performance points depending on the implementation, delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding consumer applications and consuming less than 300mW for low-power mobile devices. This translates into a large increase in processing capability while staying with the power levels of previous generations of mobile devices. Consumer applications will benefit from the reduced heat dissipation and Resulting lower packaging and integration costs.

Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basic steps of defining a magnetic frill voltage generator for a dipole antenna, and it also compares the Resulting antenna impedance with known results.
