synthesized signal later by using a decoder of the type currently marketed as described in i1%
Permit 1st Kosane III. And a composite signal denoted by q [when decoding with such a decoder,
one obtains an output signal denoted by Li, 17, LB and a vector group denoted by ˜ in FIG. 1B. .
These output signals are respectively signal components. The Rf, Lb and Rbt-included as
dominant gIg, as well as lower level signals from each of the other two channels. The signal can
be divided into 9 channels around the stereo sound field, in which case the unidirectional power

Lb and IOI), can be transmitted by monaural transmission to all signals in the hatched area by
o211LH Want to be able to transmit in monaural form to the point Ob, which these signals are
hatched by a single powder, the reason is that such signals are represented by the vertical
movement of the needle on the stereo recording board 1) This is because some monaural
playback devices can not play back. As shown by the hatching in the horizontal line in FIG. 10, it
is necessary to remove the central part of the 1 channel stereo sound field. This is not to say that
this itself does not give rise to unacceptable results, but this causes the sense to be inadequate,

which is relatively small to the central signal 0 represented by the vector sum of 0, 707 L, so that
an approximately equal amplitude 02 signal is obtained, λ signals with different amplitudes are
obtained. When played with a 7,1 player, the turtle will shift to the left in the central signal
stereo sound field.
Similar to the analysis of the vector diagram of the gtB diagram, it is evident that the KLT and RT
compensation -wI are decoded to generate one output signal, as indicated by the central part of
the LF 'and 1 and R members reproduction channels. The signal inside is relatively hot The signal

that occurs when mixing the kind of signal using the encoder of Figure 1 A solution to the above
mentioned problems is described in U.S. Patent Application No. 2 qstoo but is also described
herein to provide a complete understanding of the present invention. This rebuilt encoder is
shown in FIG. This is somewhat different from the encoder of FIG. 1 and is a turtle which offers
important advantages when later regenerating the signal as described above. In this case, the full
table-forward signal (L,) and the full right-forward signal (Rf) appearing at the input terminals to
'and / 6' are directly applied to the input terminals of the respective output summing network 37
series j2. Are provided to bypass W-networks 1 and 32, respectively. The 穐 and Rb signals
appearing at the input terminals l 'and l' di are passed through a two-network review and
viewing, respectively, as in the previous example, and after being relatively phase shifted by 900,
at an amplitude level of 0.707 The summing junction point and 12K are supplied. In this case,
the Rb signal is negative with respect to the Rb signal. L1) and Rb signals whose amplitudes have
been reduced by Jd) by summing junction 30 'and ′' are fed via V-network 32 and I to summing
junctions 5.2 and 5θ respectively Is added to the other signal. The effect of the encoder of this
example is the vector group shown in the first five figures representing the composite signal
appearing at the output terminal V 'and the case', respectively! ダおよび! It is indicated by a
bribe. That is, the relative phase relationship between the L and R1 fractions remains unchanged.
The reason is that the reference phase guess function V * is removed from these signals as well.
The relative positions of the vector t), 707 Rb and 0.707 Lb are the same as in FIG. 1A.
Essentially, the encoder of FIG. 2 introduces a derivative reference function derivative between
the rear signals Rb and Lb and the front signals Lf and R2. By introducing such a frequency
dependent function p, any coherent signal distributed between the front and back channels will
be significantly inconsistent due to the "comb filter" action.
· The 'incoherence between the front and back of the decoder is properly distributed, so that the
signal taken at the central position appears to the listener as directly above the self or one The
relative invariant position of the vector in the λ synthesized signal (which is more for voice and
musical tone signals than for this function hy-normal sine wave signal) which is distributed by
dividing between each diagonal escapes For these, these are US Patents 124,111! Can be easily
dated by an encoder. The vector diagram of the decoded signal in this case is referred to as λB1.
, Shown in the figure. While the dominant and enable signals in the "forward" channel are in
phase with each other and the dominant Lb and Rb signals in the "back" channel are also in
phase with each other, the dominant "forward" as in the @ / B diagram. Not in phase with the
channel signal. As apparent from the JIIH hatching area of the chime channel sound field shown
