Abstract :
A method of separating the sections of a lumped-constant delay line by means of short-circuited coils has been proposed by V. A. Solov´ev. The paper shows that, using this principle and an improved method of construction, the size of a delay line may be very considerably reduced. The line considered follows conventional delay-line theory closely, but differs considerably in its construction. Small size is achieved partly by an economic use of `distributed constants¿ within the sections and partly by the space-saving use of short-circuited coils. A practical method is given for the design of the delay line.
