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.
For example, if the FREQUENCY dial is set on 2.6 and the 1 LED is lighted, the function generator output frequency is 2.6 Hz. 5. FREQUENCY Range LEDs. Indicate the range (either MHz or kHz) of the reading shown on the counter readout. These LEDs also indicate the frequency range of the function generator output. For example, if the FREQUENCY dial is set on 9, the 10-1M LED is lighted, the kHz LED is lighted, and the counter readout shows .090, then the function generator output frequency is 0.090 kHz=90Hz.
