I'm finding it a useful exercise, when doing the QADV questions on Electromagnetic Compatibility, to try to draw the circuit diagrams for the following, in order to help me better remember them:
Perhaps you might benefit from the same exercise?
Here's a point which you might need to know for the EMC questions:
What is another name for a notch filter? The answer is a Band Stop Filter.
Band pass filters are constructed using:
a) capacitors alone
b) transistors and resistors
c) capacitors and inductors
d) diodes and inductors
The correct answer is c) capacitors and inductors.
Another name for 'blocking' (something that a very strong signal can cause in a receiver) is:
The answer is a) de-sensing.
If you thread a ferrite bead onto a wire, it increases the inductance of the wire.
