An Interesting Idea for Checking Crystal Filter Passbands

Today at 9:37 AM
Hi Bill,

Just listened to your last soldersmoke blog with reference to xtal filter checking using a DDS and scope. What do think of this idea to check filter performance?


 Logical, relatively easy to build and NO digital electronics to deal with. *;) winking
