Spoken like an engineer "if in doubt use a feedback loop". Makes loads of sense.
Forum (senior)members please realize that at least in India the students are quite often ignorant and sometimes misguided by their own professors, even at post graduate level. So when they come here, at times they are in dire straits. In general one of the worst things they are "taught" is: Theory and practice in electronics are unconnected, so not much point in reading datasheets or textbooks for understanding or designing.
