1. A receiver providing output signals indicative of any desired one of a plurality of security price data indicated in a succession of transmitted signals applied to said receiver, each said applied signal including a first pulse group identifying a particular security and at least a second pulse group indicative of price data pertaining to said identified security, comprising:
- a. operator-controlled means having capacity for generation of all said first pulse groups identifying each of said securities and controllable to generate any desired first pulse group;
b. first shift register and decoder means receiving said applied signals and said pulse group generated by said operatorcontrolled means and providing an output signal exclusively on correlation between first pulse groups of said applied signals and said pulse group generated by said operator-controlled means; and
c. second shift register and decoder means receiving said applied signals and having output terminals providing said receiver output signals, said second shift register and decoding means being operatively responsive to said first shift register and decoder means output signal to selectively conduct to said output terminals second pulse groups of said applied signals.

2. The receiver claimed in claim 1 further including security price data display means connected to said receiver output terminals.
-
3. The receiver claimed in claim 2 wherein said transmitted signals are modulated signals, said receiver further including means demodulating said transmitted signals for generation of said applied signals.
-
4. The receiver claimed in claim 3 further including front end and intermediate frequency circuit means for detection of signals transmitted by an FM-SCA channel.
-
5. The receiver claimed in claim 3 further including front end and intermediate frequency circuit means for detection of signals transmitted by an FM stereo channel.
-
6. The receiver claimed in claim 3 further including front end and intermediate frequency circuit means for detection of signals transmitted by a community antenna television system.
