Receiver for the reception of signals transmitted by delta modulation

DETAILED DESCRIPTION What is claimed is: 1.
A delta modulation receiver comprising means for receiving a pulse pattern of a pulse pattern group Q.
sub.
K constituted by an information pulse I.
sub.
K at an instant t.
sub.
k and a preceding information pulse I.
sub.
K.
sub.
-1 at an instant t.
sub.
k.
sub.
-1 and an information pulse I.
sub.
K.
sub.
+1 subsequent to the pulse I.
sub.
K at an instant t.
sub.
k.
sub.
+1, a pulse pattern analyzer means for distinguishing different pulse patterns of the pulse group Q.
sub.
K from said receiving means and for providing correction signals and control signals corresponding to said different pulse patterns of said pulse group Q.
sub.
K, a stepsize control circuit means responsive to the control signals from said pulse pattern analyzer means and to the received pulse patterns for multiplying the received pulse patterns by different discrete weighting factors corresponding to said control signals, and correction circuit means and connected to said responsive to said correction signals from said pulse stepsize control circuit means pattern analyzer means for modifying the multiplication of said received pulse patterns.
2.
A delta modulation receiver as recited in claim 1, wherein said pulse pattern analyzer means comprises a separate storage element for each of said pulses I.
sub.
K, I.
sub.
K.
sub.
+1 and I.
sub.
K.
sub.
-1.
3.
A receiver as claimed in claim 1, wherein the correcting signal generated by the pulse pattern analyzer for the pulse group Q.
sub.
K corrects the steps associated with at least two successive information pulses in the correction circuit when predetermined pulse patterns of the pulse group Q.
sub.
K occur.
4.
A receiver as claimed in claim 3, wherein the correction circuit has a delay element for generating a delayed output signal in addition to the correcting signal of the analyzer, said two output signals jointly constituting the control signal for the corrections of the steps associated with at least two successive information pulses.
5.
A receiver as claimed in claim 3, wherein the criterion for the analyzer to produce a correcting output pulse consists in the occurrence of a pulse pattern Q
