Can you tell me what is the meaning of Analog interface circuit and why we apply this between transducer and ADC?
Hi,
Normally, the Analog Interface Circuit contains the transducer, the ADC and other electronic components for analog signal processing.
Do you have an example of a product or a schematic which has an analog interface circuit connected between a transducer and an ADC ?
Regards,
Hi
Yes sir i found it from a block diagram.
Transducer->Analog interface Circuit->ADC->Microcontroller->DAC->Driver circuit ->Actuator.
I have to explain this for my viva exam.
As example,
Why can not connect directly transducer or actuator for MCU?
Why we use driver circuit among MCU and actuator?
Why we use Analog interface circuit between transducer and MCU?
Why use ADC and DAC?
These are some quections for my viva exam…
Hi,
The general definition of an analog interface circuit, like we mentioned, usually includes all electronic components (or circuits) needed for signal processing.
In this specific example, the analog interface circuit used in the diagram is probably for filtering electronic signals received from the transducer. It’s more likely a circuit of electronic filters to remove unwanted frequency components from the signal to be processed with the ADC (Analog-to-Digital Converter).
