Question : 164 of 200

Marks: +1, -0

In an input signal with non-zero direct current (dc) components is applied to a low pass RC network, then DC component in the output signal will be _____

The same as that in the input
Less than that in the input
More than that in the input
zero

Validate

Solution:

If non zero DC voltage is applied on input of low pass network then for DC voltage capacitor is open circuit.

X_C=1/{2π\fC}

F = 0 for DC circuit

X_C

= 00 open circuit

Then output signal is the same as input signal.
