This is a follow up on the previews article on the low and high pass filter designer. An algorithm is developed in order to perform interpolation. The FIR low pass filter from the last post is used in the interpolation…
This post is about digital low and high pass FIR filter design in VHDL. Implementing high/low pass filter in the digital domain has a lot of benefits compared to implementations in the analog domain. The VHDL code for an implementation…
This breakout board helps me to interface my FPGA with the DAC900E from Texas Instruments. The DAC has 165 MSPS and 10 bits which is quite some speed. The combination FPGA and DAC opens up for experiments with digital signal…
This is my most advanced homemade PCB design until now. The PCB contains a EP3C5E144C8N Cyclone III FPGA from ALTERA, two 8 bit ADCs AD9057 from Analog Devices @ 80 MHz, a FTDI USB2.0 controller and many other things. The…
This is a PCB design using the USB 2.0 IC from FTDI, FT232H – Hi-Speed Single Channel USB UART/FIFO IC, to connect it to the GPIO port of the Altera DE0 development board. The design should also work with other…
This project describes how to build you own Software Defined Radio (receiver part). Starting from an antenna, amplifiers, mixer, filter, ADC, FPGA a FM radio signal is received and demodulated in software. All the blocks for amplification, mixing, filtering and…
Here comes the documentation on how to write a source block for GNU Radio interfacing the FTDI FT232H USB 2.0 controller. This is particular interesting when one is willing to build an own Software Defined Radio (SDR) using an FPGA…
Recently I bought the Altera DE0 Development and Education FPGA board from Terasic. This is a project giving the development board a fast USB2.0 interface. As an USB 2.0 controller the FT232H Single Channel Hi-Speed USB to Multipurpose UART/FIFO IC…
