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 ...
The Fourier transform (FT) decomposes a signal into its constituent frequencies and shows that any signal can be re-written as the sum of sinusoidal functions. It is also a mathematical method for transforming a function of time into a function of frequency , i.e. transforming from the time domain to the frequency domain. The Fast Fourier transform (FFT) computes the Discrete Fourier transform (DFT) of a sequence.   Field Programmable Gate Arrays (FPGAs) offer a high performance and fle ...
  Many engineers have come across Digilent Pmods standard and even included Pmods in their systems. Pmod modules allow for more effective designs by routing analog signals and power supplies only where they are needed, and away from digital controller boards. However, Pmods aren't for high speed communication. So, engineers can't use Pmods in high speed instrumentation systems or digital signal processing applications. At the same time, high speed FPGA Mezzanine Cards are bulky and compara ...

This post shows how to create harmonics in a specific signal with the Analog Discovery 2 and look at the spectrum through FFT mode. We will use the Oscilloscope and Waveform / Signal Generator instruments in Analog Discovery 2.   Basic Ideas for Harmonics and Fast Fourier Transform  A harmonic is a signal whose frequency is an integral multiple of the frequency of some reference signal. Every periodic signal has its lowest frequency which is called fundamental frequency. The further s ...
