It is of importance in academic aspect to analyze the original meaning and to probe into the logic relationship among market positioning, product positioning and competition positioning.
Through a probe into a number of key concepts of his poetic theory, this paper studies the logic of Roman Jacobson's poetic criticism and the operation of his "grammar of poetry".
Making use of logic analyzer, oscillograph and bus analyzer, we can design and test the superhigh density FPGA, and transmit the signal to the instrument through probe and linker.
