TDS - Computer Controlled Teaching Unit for the Study of Digital Signal Processing

1. TDS Unit: Metallic box Diagram in the front panel with similar distribution to the elements in the real unit. Front Panel: 2 Function generators modules, that can generate 3 different signals: sinusoidal, square and triangular. Each one includes: wave forms selector, frequency selector, amplitude selector. Duty cycle selector. Signal output. Noise generator module, that can generate two noise type. Including: 2 noise outputs, attenuator selector per each noise type. Microphone pre-amplifier module, including: input ( microphone) , outputs ( 2 connectors) . Power amplifier module, including: inputs ( 2 connectors) , output ( 1 connector) , volume selector. Speaker module. PC input/ output module, including: 2 inputs. 2 outputs. Power On/ Off switch. Lateral panel: SCSI connector for connecting with the data acquisition board ( DAB) to be placed in the computer. Back panel: Power supply connector. Safety fuse. Inside: Power supply. 2 Signal generation boards ( PBC) . White and pink noise generation board ( PBC) . Power amplifier board ( PBC) . Pre-amplifier board ( PBC) . Control interface. Possibility of working simultaneously with two external signals, thanks to its inputs, facilitating operations that required more than one signal. Moreover it is possible to generate signals directly by the software and send them to the unit outputs and then visualizing by an external oscilloscope or listening by the speaker. 2. DAB. Data Acquisition Board: PCI Data acquisition board ( National Instruments) to be placed in a computer slot. 16 Analog inputs. Sampling rate up to: 250 KS/ s. 2 Analog outputs. 24 Digital Inputs/ Outputs. 3. TDS/ CCSOF.Computer Control+ Data Acquisition+ Data Management Software: Registration and visualization of signals in an automatic and simultaneously way. 2 signals can be visualized simultaneously. Flexible, open and multicontrol software, developed with actual windows graphic systems, acting simultaneously on all process parameters. Management, processing and comparison of data. Sampling velocity up to 250 KS/ s ( kilo samples per second) . Comparative analysis of the obtained data, after the process and modification of the conditions during the process. 4. Cables and Accessories, for normal operation. 5. Manuals: This unit is supplied with 8 manuals. Dimensions ( approx.) = Unit: 490 x 330 x 310 mm. Weight: 30 Kg.
