Abstract
A pulse step modulator (PSM) is presented herein for use in an AM transmitter. The modulator includes a plurality of unit step modules each including a DC voltage source and an associated actuatable switch for, when actuated, turning on the associated module to provide a unit step voltage. An output circuit is connected to the modules for providing an output voltage to a load wherein the magnitude of the output voltage is equal to the sum of all of the voltage sources of the modules that are turned on. An addressable memory is provided which has a plurality of addressable storage locations with each storing and providing, when addressed, a pattern of control signals respectively associated with the modules with each control signal being a turn on signal or a turn off signal for controlling the turn on or turn off of an associated module. The memory is addressed with an address which has a turn on portion and a start point portion. The turn on portion includes information representative of the number of modules that are to be turned on and the start portion includes information representing the address of the first of the modules to be turned on.
