A student creates a Bluetooth controlled synthesizer with Digilent Nexys Video and Pmod BT2. You can control the frequency and amplitude of 10 sine waves from the mobile apps.     Signal Processing for the Synthesizer The synthesizer is designed in additive synthesis. This involves the summation of multiple sinusoidal signals to form a more complex signal. The additive synthesis parameters in a discrete-time implementation can be determined using the Fast Fourier Transform (FFT) that ...
In the process of developing a new Xilinx Zynq SoC system, it's important to know the specifications of the hardware and see the timing of signals. Unfortunately, the speed of the QSPI transactions in the boot sequence isn’t always an evident specification. Digilent Digital Discovery and High Speed Adapter system is capable of visualizing QSPI transmission which can take place at much higher clock speeds, over 100 MHz. Because of the 512 MB DDR memory that the Digital Discovery has, it can ...
