1 Merino is one of the softest types of wool available, because of finer fibers and smaller scales.  Merino has an excellent warmth-to-weight ratio compared to other wools, in part because the smaller fibers have microscopic cortices of dead air, trapping body heat similarly to the way a sleeping bag warms its occupant.
Transistorâtransistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors.
59Appendix A-An Introduction to Frequency CalibrationsTable A.1. Frequency offset values for given amounts of phase deviation.The frequency offset values in Table A.1 can be converted to units of frequency(Hz) if the nameplate frequency is known. To illustrate this, consider an oscillator witha nameplate frequency of 5 MHz that is high in frequency by 1.16 Ã 10 -11.
