Why the delay in the flash type conversion occurs?

47

What are the
advantages of dual slope type A / D converter?

Advantages


48

Why dual type analog
to digital converter is not used in the digital acquisition application?

Due to large conversion time


49

Describe the
applications of the dual slope type A / D converter.

Digital voltmeter, multi meter etc.


50

Why the application
of Dual slope type A / D converter is limited only for low to medium
frequency?

The dual slop type A / D conversion is
limited only for low to medium frequency due to slow conversion time.


51

On which parameter
the accuracy of the Dual slope type A / D converter depends?
OR
Why the reference
voltage should kept precise in the dual slope type A / D converter?

The accuracy of the dual slop type A / D
converter depends upon the reference input voltage.


52

Are there any D / A
converter used in the voltage to frequency type DAC?
OR
Why the voltage to
frequency type ADC is simpler than any other type ADC?

The voltage to frequency type ADC is simpler
than any other type ADC because it does not use DAC.


53

What are the
application of voltage to frequency A / D converter?

Application


54

Which type of analog
to digital converter has fixed conversion time?

Successive approximation type ADC


55

Which type of the
ADC is most widely used?

Successive approximation type ADC


56

What is output of
the integrator when the input is negative constant voltage?

Positive ramp
