ans :2

C?haracteristic error

Error is defined as the difference between the measured value and true value.

The errors can be divided into five categories

Insertion error : Occurs during the act of inserting the sensor into system being measured.

Characteristic error:Errors without qualifying term.

Application error: Errors caused by the operator such incorrect usage and incorrect placement of probes for temperature measurement etc.

Dynamic errors:These include response time,amplitude distortion and phase distortion.

Environmental errors: Errors derived from environment in which the sensor is used.

Characteristic error:

This category is most often meant when discussing errors without qualifying the term.

These are the errors inherent in the device itself i.e: the difference between the ideal characteristic function of the device and the actual characteristic.

These may include

Error in dc offset value false pressure head

Incorrect slope or slope which is not perfectly linear.

Let A = 2 1 1 1 2 1 1 1 2 (a) Find the characteristic polynomial PA(λ) of A and the eigenvalues of A. For convenience, as usual, enumerate the eigenvalues in decreasing order λ1 ≥ λ2 ≥ λ3. (b) For each eigenvalue λ of A find a basis of the corresponding eigenspace V (λ). Determine (with a motivation) whether V (λ) is a line or a plane through the origin. If some of the spaces V (λ) is...
