Beckhoff Automation has extended its range of IP 67 I/O modules with the newEP4374 EtherCAT Box. This flexible, moisture and dust-resistant I/O devicecombines two analog inputs and two analog outputs ...

If the input drive circuitry does not permit the analog input signal to settle to the correct value, the conversion will be incorrect. Figure 1 is a simplified model of a SAR ADC input stage.

Debugging embedded systems and circuit power is often an exercise in having enough analog or digital inputs. The MSO5 series mixed-signal oscilloscopes from Tektronix provide an unprecedented ...

Once you know the volts/bits ratio, you can design signal-conditioning circuits that convert the analog-input signal to the appropriate input-voltage range for the ADC. Two examples help illustrate ...

Instead the circuit [Mincepi] is using consists only of passive components, measuring the time taken to discharge the parasitic capacitance of one of the Pi’s inputs from logic 1 voltage to ...

Input devices that can handle rough and tumble environments aren’t nearly as varied as their more fragile siblings. [Alastair Aitchison] has devised a brilliant way of detecting inputs from p… ...

I have my digital inputs properly assigned, and the receiver is processing them as "digital"--it's just that the digital inputs won't pass a signal to the analog rec outs. Believe me, I tried.

Vicon Industries, a leading designer and producer of security surveillance solutions, introduces a 16-channel H.264 video encoder model that converts analog camera inputs into streamed IP video data.

Input-referred voltage noise, for example, consists of flicker (1/f) noise, which dominates at lower frequencies, and thermal noise that affects higher frequencies.
