A monostatic pulsed radar operating at 30 GHz has a transmitter with 2 KW O/P power and an antenna with 30 dB gain. Minimum detectable signal in the receiver is -100 dBm. Determine the maximum range of the radar, if it is required to detect a target having radar cross section of 10 sq.m (consider log 10 4π = 1.1). Assume EM wave propagate under ideal conditions.
How many voice channels are supported for each 30 KHz radio channel in IS-136?
The transfer function of a phase lead network, as shown in the figure below is $$\frac{{K\left( {1 + 0.3s} \right)}}{{\left( {1 + 0.17s} \right)}}$$ The values of R 1 and R 2 are respectively
Consider the following statements pertaining to the resistance of a conductor: 1. Resistance can be simply defined as the ratio of voltage across the conductor to the current through the conductor. This is, in fact, Georg Ohm's law 2. Resistance is a function of voltage and current 3. Resistance is a function of conductor geometry and its conductivity Which of the above statements are correct?
If the electric field established by three point charges Q, 2Q and 3Q exert a force 3F on 3Q and 2F on 2Q, then what is the force exerted on the point charge Q?
