If p-transistor is conducting and has small voltage between source and drain, then it is said to work in . . . . . . . . The ROC of z-transform of the discrete time sequence $$x\left( n \right) = {\left( {{1 \over 3}} \right)^n}u\left( n \right) - {\left( {{1 \over 2}} \right)^n}u\left( { - n - 1} \right)$$ is Consider the following statements relating to communication satellite systems: 1. The geosynchronous orbits of the satellites are in the earth's meridional plane. 2. It is not necessary to incorporate a very low noise amplifier in the satellite as the noise temperature of the satellite antenna will be high. 3. The total delay on one round trip is about one quarter of a second which is near the limit of satisfactory two - way telephone communication. Select correct answer out of these statements Consider the following statements for signal flow graph: 1. It represents linear as well as non-linear systems. 2. It is not unique for a given system. Which of the above statements is/are correct? MUF is depend upon
