Electronics and Communication Network Theory And Analysis Difficulty: Medium

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 Which is the first company who defined RISC architecture? If a certain Zener diode has a Zener voltage of 3.6 V and reverse bias voltage of 5 V is applied across it, the Zener operates in . . . . . . . . Companding in PCM systems lead to improved signal to quantization noise ratio. This improvement is for The typical squelch circuit cuts off
