Designing Analog circuits

I am currently reading Troubleshooting Analog circuits by Robert Pease as I have been in testing for a last few years and still learning.

I want to know if someone can recommend a book for troubleshooting.
I also want to read a book on designing and want to get into it.
Can someone recommend the books please?

Thanking you,

for designing and understanding electronics circuits, i recoment "Floyd, 5Th eddition "
