PURPOSE:To attain very simple circuit constitution by providing a pseudo noise signal generating section generating a single pole pseudo noise signal and an analog switch turned on/off in response to the said pseudo noise signal and receiving a reception spread signal via a capacitor. CONSTITUTION:An analog switch 1 is provided, which receives a reception SS signal (reception spread signal) via a capacitor C1 and a resistor R1. Moreover, a pseudo noise signal generating section 2 generating a single polarity (0, 1) PN code (pseudo noise signal) is provided and connected to the analog switch 1. The analog switch 1 is turned on/off by the PN code and since the PN code is of single polarity, the operation for the sum of products is implemented only by the on/off of the analog switch. |
