- 333: Digital Block For A Fucntion Generator
- ... to other parts of this function generator namely the amplifier module. Also a filter selector circuit is built in after the digital block. The user inputs controlling frequency and symmetry are also built into this control block. Therefore it is clear that the digital block can be divided into 4 distinct blocks, each with its own functionality. These blocks are the control module, counter module, filter control module and 8-bit D/A. The D/A chosen is the DAC0801LCN. It s specifications can be found in the appendix. The layout of this design is shown below. The interconnections will be ...

- 336: Ultrasonic Radar for a Home PC System
- ... speaker. It emits an ultrasonic pulse then waits for the echo to return. The ranging board is the second part (Fig. 2). This board provides the high voltages required for the transducer, sensitive amplifiers, and control logic. Since R1 is variable it controls the sensitivity of the echo detector. A stepper motor rotates the transducer to get a 360o field of view. For entire assembly see Figure 3. An Experimenter is hooked up to the ranging board to control the ranging board and to measure the round trip time of pulses. It also controls the stepper motor and communicates with the control computer. The connections between the Experimenter, ranging board, and transducer are shown in Figure 4. The ranging board's power requirements are usually under a 100 mA, but at peak transmission the circuit can ...
