Scientech Technologies Interview Questions and Answers

Active filters are electronic circuits that use active components to filter out unwanted signals from a circuit.

• Different types of active filters include low-pass, high-pass, band-pass, and band-stop filters.

• Designing an active filter involves selecting the appropriate filter topology, choosing the cutoff frequency and gain, and selecting the appropriate active components such as operational amplifiers.

• For example, a S...read more

Ripple power supplies are electronic devices that convert AC voltage to DC voltage with a small amount of AC ripple.

• They are commonly used in electronic devices such as computers and televisions.

• The ripple voltage can cause interference with sensitive electronic components.

• Ripple power supplies can be regulated or unregulated.

• Regulated ripple power supplies use feedback to maintain a constant output voltage.

• Unregulated...read more
