Abstract: A transmitter is capable of suppressing a PAPR to be low and efficiently amplifying transmit power. The transmitter generates a transmission signal by oversampling a modulated signal, and includes a modulation unit that performs a modulation process on an information sequence and that generates a constant envelope signal and a phase interpolation unit that inserts a predetermined number of signals identical in amplitude to signal points of the constant envelope signal between the signal points so that signal points including original signal points are located equidistantly.

Abstract: A secondary battery or capacitor fitted with terminals and occupies less area on a packaging substrate. Either one of the positive and negative terminals is mounted within the outer surface of the secondary battery or capacitor. This reduces the area occupied by the secondary battery or capacitor fitted with terminals on the substrate. At least one step is formed on the terminal positioned opposite to the substrate. This prevents electrical shorting between the positive electrode can and the negative terminal.
