© 2009 - 2020 by IndiaBIX™ Technologies. A stopband is a band of frequencies, between specified limits, in which a circuit, such as a filter or telephone circuit, does not let signals through, or the attenuation is above the required stopband attenuation level. Amplification and switching. 14. UHF waves travel as : (c) astable multivibrator (d) Schmitt trigger, 81. one of the following can be used to generate a pulse when ever triggered: i want ta these 200 question of communication system. Transistors have two main functions, what are they? People speaking the same language can understand each other, but not other people.
