if a feeder having a characteristic impedance of 400 ohm is to be connected to an antenna having the impedance, calculate the spacing of quarter wave parallel wire feeder to be inserted between the two if the diameter of the wire is 3mn. 2)Draw LS-TTL NOR gate circuit 3)explain slope overload in digital communication 4)compare open collector output and totempole output?
