The Digital Signal Processing is a mathematical manipulation of the data signal to adapt and improve the input signal in some way. Some examples of the digital signal processing are: digital noise reduction, signal filtering etc.

The digital signal processing helps to reach a reliable communication links with high data transfer rates and good noise rejection. The Teaching Unit for the Study of Digital Signal Processing “TDS” allows to understand the principles of digital signal processing and signal analysis.


With this unit there are several options and possibilities:

 - Main items: 1, 2, 3, 4 and 5.

 - Optional items: 6.

Let us describe first the main items (1 to 5):

1. TDS. Unit:

 Unit mounted in a metallic box.

 2 Function Generators modules, each one includes:

 Waveform selector: sine, square and triangular.

 Frequency potentiometer, range: 20 Hz to 20 KHz.

 Amplitude potentiometer, range: ± 10 V.

 Duty cycle potentiometer, range: 0% to 100%.

 BNC output connector.

 Noise Generator module:

 White noise generator:

 Amplitude potentiometer, range: ± 10 V.

 BNC output connector.

 Pink noise generator (also called frequency inverter or noise 1/):

 Amplitude potentiometer, range: ± 10 V.

 BNC output connector.

 Microphone Pre-Amplifier module:

 It adapts the microphone signal to be analyzed by the data acquisition system or by the speaker.

 1/4’’ jack input connector for the microphone.

 BNC output connector.

 Microphone:

 Impedance: 500 .

 Frequency response: 70 Hz to 14 KHz.

 1/4’’ jack connector.

 Power Amplifier module, including:

 BNC input connector.

 

 BNC output connector.

 Potentiometer to regulate the power amplifier gain.

 Speaker module:

 Impedance: 8 .

 Nominal maximum power: 30 W.

 Frequency response: 100 Hz to 13 KHz.

 PC input/output module, including:

 2 BNC input connectors.

 2 BNC output connectors.

 SCSI connector to the data acquisition board (to be placed in the computer).

 Possibility of working simultaneously with two external signals, facilitating operations that require more than

one signal.

 Moreover, it is possible to generate different waveforms by the software and send them to the outputs of the unit.

These signals can be visualized by an external oscilloscope or be listened by the speaker.

 The complete unit includes as well:

 Specialized EDIBON Control Software based on Labview.

 Projector and/or electronic whiteboard compatibility allows the unit to be explained and

demonstrated to an entire class at one time.

 Capable of doing applied research, training courses, etc.

 Remote operation and control by the user and remote control for EDIBON technical support, are

always included.

 Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).

 Designed and manufactured under several quality standards.

 

2. DAB. Data Acquisition Board:

 PCI Express Data acquisition board (National Instruments) to be placed in a computer slot. Bus PCI

Express.

 Analog input:

 Number of channels= 16 single-ended or 8 differential.

 Resolution=16 bits, 1 in 65536.

 Sampling rate up to: 250 KS/s (kilo samples per second).

 Input range (V)= 10 V.

 Data transfers=DMA, interrupts, programmed I/0.

 DMA channels=6.

 Analog output:

 Number of channels=2.

 Resolution=16 bits, 1 in 65536.

 Maximum output rate up to: 900 KS/s.

 Output range(V)= 10 V.

 Data transfers=DMA, interrupts, programmed I/0.

 Digital Input/Output:

 Number of channels=24 inputs/outputs.

 D0 or DI Sample Clock frequency: 0 to 100 MHz.

 Timing:

 Counter/timers=4.

 Resolution: Counter/timers: 32 bits.

 TDS/CCSOF. Computer Control +Data Acquisition+Data Management Software:

 Compatible with actual Windows operating systems.

 Graphic and intuitive operation.

 Compatible with the industry standards.

 Registration and visualization of signals in an automatic and simultaneous way.

 2 signals can be visualized simultaneously.

 2 signals can be generated simultaneously.

 Totally configurable digital filters: Infinite Impulse Response (IIR) filter and Finite Impulse Response

(FIR) filter.

 Totally configurable analog filters: Butterworth filter, Chebyshev filter, etc.

 Visualization of frequency and time response of the signal before and after filter.

 Visualization of each input signal and the signal result of the combination of the two input signals.

This signal combination allows the study of the generated signal (sine, square and triangle) or the user voice

(with the microphone and microphone pre-amplifier) when a white noise or pink noise is added to the signal.

 Management, processing, comparison and storage of data.

 Sampling velocity up to 250 KS/s (kilo samples per second).

 Cables and Accessories, for normal operation.

 Manuals: This unit is supplied with the following manuals: Required Services, Assembly and Installation,

Interface and Control Software, Starting-up, Safety, Maintenance & Practices Manuals.
