List-I is four different semiconductor devices. Match each device in List-I with its characteristic property in List-II . List-I List-II a. BJT 1. Population inversion b. MOS capacitor 2. Pinch-off voltage c. LASER diode 3. Early effect d. JFFT 4. Flat-band voltage Karnaugh map is used to Which one of the following multivibrators does not required input clock pulse or trigger? Digital filters have . . . . . . . . and are best suited for . . . . . . . . phase. Given that h(t) = 10e -10 u(t), and e(t) = sin10t.u(t), the Laplace transform of the signal $$f\left( t \right) = \int\limits_{\tau = 0}^t {h\left( {t - \tau } \right)e\left( \tau \right)d\tau } $$ is given by
