I have to build a modest version of a digital oscilloscope with the following specs
Pre-trigger/pos-trigger time: 2 seconds
sampling rate: 2.4khz.
Storage format: COMTRADE
Channels: 8 analog channels/16 digital channels
Advice is required for deciding the architecture for the above design
my first take on this:
1. Use AD7606 for acquiring analog channels and connected to FPGA
2. connect digital inputs to FPGA
3. Connect SPI NVRAM, RTC to FPGA for data storage/time stamp
4. Use Microcontroller to convert data (read from FPGA) to COMTRADE after the acquisition is complete
Pl suggest the efficient algorithm to be implemented in FPGA for implementing oscillograph.
