The implementation of Hdb3 encoding based on FPGA

HDB3 code is a bipolar NRZ based on the improvement of the AMI code, not only does it have no DC component in the power spectrum, like the AMI code, and can be self-test error, etc., but also overcomes the time extraction difficulty when there is continuous "0" appears in the AMI...

spartan 3 VHDL time set and reverse counter with BCD

The spartan3 Starter Kit board is used to set time and Count down to 0.Each Digit is available to set by push button next_d. The value is able to change by button plus or minus.Switch 'start' is used to Count down the or set the time.The Display Shows hours and mins or Switch stt is 'on' it Sho...
