Answer :

ADC-Amplifier interface:

In most data acquisition system analog to digital converter (ADC) is interfaced with the amplifier. There are different interface architectural schemes. Operational amplifier performs basic signal conditioning ahead of analog to digital converter. The interaction between analog to digital converter and amplifier affects the system performance.

Description : Which type of ADC gives high resolution?

Answer : Sigma Delta, successive approximation and integrating type analogue to digital converter gives very high resolution but they have slower speed.

Description : The ADC having highest conversion speed is (A) Dual-slope ADC (B) Successive approximation ADC (C) Flash ADC (D) Servo ADC

Answer : The ADC having highest conVersion speed is Flash ADC

Description : Describe the various blocks and their functions in pipelined ADC architecture.

Description : Integrating or Dual Slope ADC

Answer : Operation: At the start of measurement the counter is reset to zero. So output of flip-flop is zero. This is applied to the switch control. The switch control now connects input voltage (Vin) to ... Then the data from counter is passed to the digital readout for display purpose.

Description : Define ADC and DAC. Write two applications of each.

Answer : ADC An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by ... signal, hence any analog circuit can work with digital system Application - Microcontroller, washing machine
