1 TDS. Unit: Diagram in the front panel with similar distribution that the elements in the real unit. Steel box. Front Panel: 2 Function generators modules, that can generate 3 different signals: sinusoidal, square and triangular. Each function generator includes: Wave forms selector ( sinusoidal, square and triangular) . Frequency selector. Amplitude selector. Duty cycle selector. Signal output ( BNC connector) . Noise generator module, that can generate two noises type. Including: 2 noise outputs: one for white noise and other for pink noise. Attenuator selector per each noise type. Microphone pre-amplifier module, including: Input ( microphone) ( jack connector 1/ 4’ ’ ) . Outputs ( 2 connectors, one jack connector 1/ 8’ ’ and the other BNC connector) . Power amplifier module, including: Inputs ( 2 connectors, one jack connector 1/ 8’ ’ and the other RCA connector) . Output ( BNC connector) . Volume selector. Speaker module. PC input/ output module, including: 2 inputs ( BNC connectors) . 2 outputs ( BNC connectors) . Power On/ Off switch. Lateral panel: SCSI connector for connecting with the data acquisition board ( DAB) to be placed in the computer PC. EXERCISES AND PRACTICAL POSSIBILITIES Practical Possibilities of the unit: 1.- Continuous wave form generation, with the possibility of varying the frequency and amplitude of signals, besides of duty cycle. 2.- Characterization of signals. To analyze the nature of the signals: sinusoidal, square, triangular and sawtooth. 3.- Possibility of working simultaneously with two external signals. 4.- Possibility of generating signals directly by the software and send them to the unit outputs and then visualizing or listening by the speaker or an external oscilloscope. 5.- Signal digitalization, permitting the most suitable sampling time, avoiding “ aliasing” . 6.- Digitalization of signals with the possibility of adjusting the sampling frequency. 7.- Fast Fourier Transforms ( Power Spectrum) . 8.- Addition, subtraction, multiplication, convolution and auto-convolution of signals. 9.- Study of “ aliasing” . 10.- Application of the frequency convolution theorem.
