2.  Our proposed project is a digital oscilloscope with playback function that provides almost any function of a typical oscilloscope, such as digital sampling, signal processing, auto-scale setting, cursor setting, reconstruction and visualization of signals. Additional features such as recording and replicating signals as a function generator, interacting with PC via USB and GUI display of signals will also be included.

4.  Portability: must be easy to transfer by hand.  Light-weight: 20 lbs or less in total weight.  Packaging material: Firm plastic case.  Operating environment: ±10 ºC around room temperature.  Accessibility: User friendly interface (keypad, RPGs, and VGA).  External connections: Power supply, analog output, and VGA output socket.

5. Agilent 54621A  The typical Oscilloscope we can see in every EE lab.  Positive aspects:  Relatively high sampling rate.  User-friendly interface.  Sufficient functions for lab use.  Negative aspects:  Too heavy.  Mono-color.  No play-back function.  Expensive (~$3,000).

6. DSO Nano oscilloscope V2  A pocket-size device designed for basic EE tasks.  Positive aspects:  Compact and easy-portable (palm size).  Color display.  Abundant measurement.  Built-in function generator.  Inexpensive ($94).  Negative aspects:  Relatively low sampling rate.  Limited screen size.  Short battery life.
