Anything related to analog-to-digital converters (ADCs). ADCs are hardware devices that convert analog signals to digital signals.

These devices are extensively used to interface digital equipment (such a computer or a microcontroller) with the external world, since they allow, when coupled with suitable transducers and signal-conditioning hardware, to convert any continuous physical quantity to a number representing its value.

See the Wikipedia article on ADCs

Verilog Peak detection

I am new to Verilog. I am trying to detect peak to peak voltage of an input signal to ADC on FPGA. Before that I wanted to test a simple but similar code which finds the minimum and maximum of set of 4 bit parallel inputs. Initially I assigned…

How can I compress cyclic data with minimal code?

I need to collect data from a sensor and compress (lossy) about 2 to 1. I would like to aim for under 50 lines of C code. The signal is from a 4 bit A/D converter and is roughly a sine wave with slightly erratic amplitude and frequency. There are…

Can we send data across an analog phone line?

I wish to know whether it is possible to send data across PSTN network. While the call is in progress, I want to send some data through the telephone line (as DTMF tones can be sent). The data that I want to send is digital and is encrypted and…
