A system has a powe gain of 52. Directivity is measured as 90 and the dissipated power in an antenna with a gain of 700 is 1.9 watts. what is the EIRP in watts and dBm?
What algorithm (step by step list) can show how to multiply any two four digit numbers in any number base. The aim is to explain any base multiplication to a machine possessing artificial intelligence, that is presently oblivious as to how to do m..
The question considers the design of a 8x1 multiplexer using gates. Assume the data inputs are I0,...,I7 and the select inputs are S2, S1 and S0. (a) Write a sum-of-products expression for the 8x1 multiplexer.
A 60-Hz, single phase source with V= 277 at angle 30 degree volts is applied to a circuit element. Determine the instanaeous power, real power, and reactive power absorbed by determine the source power factor and state lagging or leading.
