When a unit ramp input is applied to the unity feedback system having closed loop transfer function

$\frac{C\left(s\right)}{R\left(s\right)}=\frac{Ks+b}{s^2+as+b},(a>0,b>0,K>0)$, The steady state error will be

The transfer function C(s) of a compensator is given below.

$C\left(s\right)=\frac{\left(1+\frac{s}{0.1}\right)\left(1+\frac{s}{100}\right)}{\left(1+s\right)\left(1+\frac{s}{10}\right)}$

The frequency range in which the phase (lead) introduced by the compensator reaches the maximum is

Two resistors with nominal resistance values R₁ and R₂ have additive uncertainties ΔR₁ and ΔR₂, respectively. When these resistances are connected in parallel, the standard deviation of the error in the equivalent resistance R is

A stationary closed Lissajous pattern on an oscilloscope has 3 horizontal tangencies and 2 vertical tangencies for a horizontal input with frequency 3 kHz. The frequency of the vertical input is

For a 3-input logic circuit shown below, the output Z can be expressed as
