to show the waveform of audio file and play it on computer
Purpose: Familiar with WAV file format and UI design
It should have the following functions:
Provide a Graphic User Interface for user to browse the file system and select one WAV file
Show the waveform of input audio signal
Play the selected WAV file
Print the parameters of WAV file such as sampling rate, bit-depth, etc
This m file models a DPSK UWB system using a delay in one leg of the mixer, correlation receiver low pass filter combination requiring no template for synching. Various waveforms are displayed throughout the system to allow the user to observe operation of the system.
Models UWB TX and RX using BPSK fifth derivative.
MATLAB Release: R13
Description: This m file models a UWB system using BPSK with the fifth order derivative of the gaussian pulse with correlation receiver and intgrator.
This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations for the Gaussian pulse waveforms. The first derivative is considered to be the monocycle or monopulse as discussed in most papers. The second derivative is the waveform generated from a dipole antenna used in a UWB system. Other information is contained in the file.

The tar file contains the following files:
ptfsf.c: heart of the perfect TFSF code
ptfsf.h: header file for same
ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper
ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields
ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file
fdtdgen.h: defines macros used in much of my code
Makefile: simple make-file to compile programs
Also include are some simple script files to run the programs with reasonable values.
The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file.
• Assume a file with correct data (no garbage, characters, etc.).
• you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour:
o If size = 0, then print a message “Size = 0 is unacceptable” and continue by reading the
next size for the next 2 matrices (if not end of file).
o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and
discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).
