  • Q2
    What is the main difference between passive and active filters?
    Active filters are more expensive than passive filters
    Passive filters do not require an external power source, while active filters do.
    Passive filters have a higher cutoff frequency than active filters
    Passive filters can amplify signals, while active filters cannot

  • Q3
    What does a high-pass filter do?
    Attenuates low frequencies and allows high frequencies to pass through
    Attenuates all frequencies equally
    Attenuates high frequencies and allows low frequencies to pass through
    Has no effect on the frequencies

  • Q6
    What is the main function of a band-stop filter?
    To attenuate or reject a specific range of frequencies while allowing all others to pass through
    To eliminate all frequencies except a specific range
    To pass only frequencies within a specific range
    To amplify all frequencies equally

  • Q7
    In a passive RC low-pass filter, what role does the resistor play?
    The resistor blocks low frequencies
    The resistor determines the gain of the filter
    The resistor sets the cutoff frequency of the filter
    The resistor allows high frequencies to pass through

  • Q8
    What is the main advantage of an active filter over a passive filter?
    Active filters have a higher cutoff frequency than passive filters
    Active filters dissipate less power than passive filters
    Passive filters are more cost-effective than active filters
    Active filters can provide amplification and have lower insertion loss compared to passive filters.

  • Q10

    Choose the CORRECT statement of the filter.

    Passive implementations of linear filter are based on combination of resistors, inductors,capacitors and transistor

    Active filters are implemented using a  active component only

    Two types of filter are passive filter and active filter.

    Active filters cannot achieve resonance without the use of inductors
