3.  An ability to sample analog voltage signal range from -12 V to 12 V via BNC;  An ability to reconstruct and display the sampled signal on VGA display;  An ability to create user interface and realize basic signal measurements, such as frequency and peak-to-peak voltage;  An ability to store/load the sampled signal to/from external memory;  An ability to replay a stored signal.

4.  Self Adjusting Oscilloscope Patent Number: US 4743844  Method And System For Secure Digital Triggering For An Oscilloscope Patent Number: US 7860674 B2  Oscilloscope System For Acquiring, Processing, And Displaying Information Patent Number: US 4225940

5.  Substantial Similarities: ◦ Same structure in sampling ◦ Similar user interfaces ◦ Store waveform to memory ◦ Display Controller/ Driver ◦ Utilize Microcomputer, RAM and ROM  Distinct Differences: ◦ Analog to Digital conversion through ADC channel on the MCU ◦ Display via VGA output and controlled by FPGA ◦ Playback the stored waveforms

6.  Substantial Similarities: ◦ Similar trigger methodology with slope detector ◦ Same sampling and comparison process  Distinct Differences: ◦ 3-points detection algorithm (in MCU) ◦ Dynamic trigger setting available

7.  Substantial Similarities: ◦ Input sampling with A/D converter ◦ Sampled data will be stored in to memory waiting for processing ◦ Reconstruct signal for display  Distinct Differences: o Use TIMER delay to plot x-axis o Digital reconstruction via FPGA, no D/A converter needed

8.  Yes because… ◦ The product is already in the market and some functions are literally the same. ◦ Same tasks are performed in substantially the same way (i.e. A/D conversion, user interface…)  No because… ◦ Different way to achieve some tasks (i.e. Input attenuation, display control and triggering algorithm).
