Is there any use of learning analog electronics?

Hi Santosh, Welcome onboard to the world of Electronics. First of all, the use of analog electronics is required in embedded system depending on, which project you are building. The common things which is needed are Analog-Digital conversion, Audio Processing, Filters, Switching circuits etc. So you should focus on these areas depending on your requirements. Hope this helps!!!

Electronics is a small part of Electrical and analog electronics is a small part of Electronics. The Analog world is highly required for the usability of the Digital system. Even a larger market share of power electronics, audio electronics, RF communications uses the Analog Electronics protocol. So, it is important to learn analog electronics even in the era of Digital electronics. It will be still relevant in the future too. 

Hi. It's been around 2 years since I moved on from Arduino. Now I have been programming AVRs directly for sometime. Thinking of starting ARM. I would like to know if there is any benefit of learning analog electronics before I start learning ARM? (I know it is not a prerequisite) I have been learning about op amps, their uses, their maths etc. Do you guys frequently encounter circuits that deal with analog circuits? If yes then I would like to know where? Audio? Environment sensing.
