A ferromagnetic material is one that forms a resistance to magnetic fields.

More Questions from Shift Registers

• A counter has a specified sequence of states, but a shift register does not.
• To transmit parallel data over a serial cable, the data must first go through data conversion to the serial format.
• Using separate serial inputs for shifting left or shifting right is a major difference between the 74194 and other shift registers.
• One of the stages in a register consists of a latch.
• A ring counter is a register in which a certain pattern of 1s and 0s is continuously outputted in parallel.
• A parallel load operation is asynchronous, so it is not dependent on the clock.
• Practically every possible load, shift, and conversion operation is available in a shift register IC.
• A universal shift register has both serial and parallel input and output capacity.
• Bidirectional means having two states.
• There are several ways to construct a stepper motor to achieve digitally controlled stepping action. One possibility is to construct four stator coils set up as four pole pairs, each 45° apart and using three ferromagnetic pairs spaced 60° apart.
