What is the need for an infinite loop in Embedded systems?Infinite Loops are those program constructs where in there is no break statement so as to get out of the loop, it just keeps looping over the statements within the block defined.Example:While(Boolean True) OR for(;;);{//Code}Embedded systems need infinite loops for repeatedly processing/monitoring the state of the program. One example could be the case of a program state continuously being checked for any exceptional errors that might just occur during run time such as memory outage or divide by zero etc.,For e.g. Customer care Telephone systems where in a prerecorded audio file is played in case the dialer is put on hold.
Also circuits being responsible for indicating that a particular component is active/alive during its operation by means of LED's.
How does combination of functions reduce memory requirements in embedded systems?The amount of code that has to be dealt with is reduced thus easing the overhead and redundancy is eliminated in case if there is anything common among the functions.

Big project.. Lots of SMD soldering. Luckily they are using larger (size 1206) SMD parts.
Norcal is legendary for offering cool kits.. This is called the Norcal 2030 because it can be built to operate on either the 20 or 30 meter band (it is a single band rig when it is done..)
What is so unusual about this rig is that the reciever is supposed to have an unbeatable noise floor and no filter ring whatsoever. I have listened to audio comparisons between it and other rigs and the lack of filter ring is pretty easy to notice.
