Abstract : A simple linear filter consisting of a delay element and an adder is described for converting a random stream of binary pulses into a stream of ternary pulses. An interesting aspect of the stream of ternary pulses is that its power spectral density is exactly the same form as the power spectral density of the binary pulses (i.e., sin squared x/x squared) except that the frequency scale is reduced by a factor of two. Another simple linear filter is described for reconverting the stream of ternary pulses into the stream of binary pulses. Results of an experimental implementation of such a system are presented. Also, a generalization of this scheme for binary to N-ary to binary conversion is discussed. (Author)
