Today, 12:21FvM replied to a thread In distributed amplifiers, is it total input capacitance of the gain stage or Cgs in RF, Microwave, Antennas and OpticsSeriously, does the discussion about terms help in any way to answer the original question? Does the term "artificial transmission line" clarify...4 replies | 208 view(s) -
Today, 11:49The swing example is inappropriate for the original gyroscope problem. Swing involves periodical transfer between potential and kinetic energy. Work...31 replies | 741 view(s)

Today, 10:50dpaul replied to a thread How do i read or write to ram address given in datasheet? using verilog in PLD, SPLD, GAL, CPLD, FPGA DesignAs mentioned above, you need to provide the bus info connecting the RAM. Then you need to drive those bus signals for READ or WRITE cases.2 replies | 80 view(s) -
Today, 08:19Doesn't sound bad in general, but some details aren't quite clear. Do you mind to share a CAD drawing of the intended sensor mount?1 replies | 85 view(s)
