The forward amplification factor of a transistor corresponds to A resistance strain gauge is cemented to a steel member, which is subjected to a strain of 2 × 10 -6 . If the original resistance is 100 Ω and change in resistance is 600 µΩ, the gauge factor will be In case of antenna the ratio of the power radiated in the desired direction to the power radiated in the opposite direction is known as Consider a real-valued base-band signal x(t), band limited to 10 kHz. The Nyquist rate for the signal $${\text{y}}\left( {\text{t}} \right) = {\text{x}}\left( {\text{t}} \right){\text{x}}\left( {1 + \frac{{\text{t}}}{2}} \right)$$ is The colour band on the extreme left in general purpose fixed resistors represents:
