I've been wondering about crystals. Not much information in my '99 ARRL handbook (unless i missed it). Or if someone could point me to a good tutorial on crystals that would be great.
Here's what I'm wondering.
1. How easy is it to replace an LC circuit with a crystal? Would one need to make changes to the circuit in order to allow a crystal, or is it not very hard? The point of this question is to see if a crystal is basically like an LC circuit.
2. What is meant by a crystal reference?
3. How does one take for example a 1MHZ crystal and use it to make 3MHZ?
4. If I remember right, a series LC circuit will only let past a certain frequency, and a parallel LC circuit will let past everything accept a certain frequency (did I get that part right?). So does a crystal behave as a series or parallel LC circuit when used as a filter? Or can a crystal not be used as a filter?
Thanx for the info :wink:
