What is ADC in SDR?
In the ultimate software-defined radio (SDR), the input from the antenna is connected directly to the analog-to-digital converter (ADC). All the filtering, demodulation, and other processing then are done in DSP. Such radios already exist for the lower frequencies.
What is ADC and DAC?
Background: Digital-to-Analog converters (DACs) and Analog-to-Digital converters (ADC) are important building blocks which interface sensors (e.g. temperature, pressure, light, sound, cruising speed of a car) to digital systems such as microcontrollers or PCs.
What is ADC architecture?
The SAR ADC is the commonly used architecture for data acquisition systems that are widely employed in medical imaging, industrial process control, and optical communication systems. In these applications, we usually need to digitize the data generated by a large number of sensors.
Which ADC requires DAC in its architecture?
First-order sigma-delta ADC. The heart of this basic modulator is a 1-bit ADC (comparator) and a 1-bit DAC (switch).
