Signal System Software

This program is actually an analog-to-digital converter. It is intended to digitise the signal coming from the soundboard. There are two modes of operation: (i) input-signal (oscillograph) mode and (ii) spectrometer mode - can be used as the recording device of a spectrometer IKS-29.

Signal Calculator v2 can covert dBM and dBV to a RMS Voltage or a Peak Voltage. The impedance can also be changed to suit. The program was developed to aid me in the design of telecomunications hardware and has been helpful in solving many problems quickly...

Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. This is a Fortran Calculus demo application.

CamPSA uses Windows Multimedia device for detection movement. It makes snapshots of the movement under jpeg format, making it usable as an observation or security system. It can send out a wav sound or send the jpg file on a client when detecting motion. You can also feed video back for realtime viewing locally or remotely.

A simulation of a NYC Transit Authority train traveling by automatic signals with working stop arms. Working circuit drawings show how the signal system relays function while the train passes over track circuits. Good learning tool. Real photos used in the program design.

Scientists and engineers can perform complex signal analysis without programming by selecting menu items that determine how the computer will analyze and present data. Selecting a processing step or algorithm causes the software to provide further menus or windows so users can tailor performance to their needs. After the user makes a processing selection, the software immediately presents processing results in 2-D or 3-D views.

The audio frequency sinusoidal signal generator is intended for adjusting and measuring parameters of audio equipment. Independent channels frequency and amplitude controls. A step of frequency setting is 0.00001 %; level - 0.001 dB; phase - 0.001 degree. The minimum coefficient of nonlinear and intermodulation distortion, precision, stability and range of frequency are limited only to quality of the used sound card.

MiniHelp! is a PHP script that allows you to interact with your visitors, offering support and/or sales in real time through chat. When the visitor requests help, the operator is informed through a visual and sonorous signal. MiniHelp! is completely Web-based, and does not require any additional software or plugin.

DAL FLUTE is a hybrid flute emulator combining multi-samples of real flutes with a Digital Signal Processing (DSP) engine. - Hybrid Synthesis that combines sample-playback engine with native DSP processing.  - Powerful multi-mode filters, envelopes, and LFOs give a wealth of creative possibilities. - Flute Selector: Normal, Bright and Pan Flute - 24 presets redesigned in a wide range of styles - Full MIDI Automation

This program allows you to record lectures with written notes attached, plus it saves both components to a single lecture file. Audio signal is compressed on-the-fly, you can export it easily and listen in transcription playback mode when necessary.
