Having covered some of the theory in the last post I am now ready to design a concrete device. Designing a Device These are the features of the device I…
One skill I wanted to learn for a long time was how to program an FPGA. As my recent hardware porjects had turned out really well I now felt ready…
In this post I am going to explain some features of the device's firmware. Firmware The LCRH7…
Based on the ideas developed so far I built a prototype. …
In this part I am are going to take a dive into LCR measurement theory and finally derive formulas for computing measurement results and we will find a way to…
In this part I am exploring a way to implement the filters for the lock-in amplifiers of the meter.Trying to design a low pass FIR filter with one of the…
I continue with the design of the LCR meter, draw a simplified schematic of the box and design the C-code for a DDS generator we can use for hardware and…
Is it possible to build an LCR meter without an FPGA or any fancy DACs, ADCs and DDS chips for signal generation, just using the analog capabilities of the MCU,…
