He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

The second was to show a live real-time end-to-end chain consisting of High Definition (HD) source material, a DVB-T2 modulator, a DVB-T2 demodulator and an MPEG-4 video decoder showing pictures ...

In this paper, BPSK modulator and demodulator are purely design by using Hardware Description Language (VHDL) and implementing it on Spartan 3E FPGA kit. From the hottest programming languages to ...
