To provide radio communication equipment by which an analog signal of sound, a picture, etc., is digitized without using compression and extension technique accompanying A/D conversion and transmission of high quality picture lawful to a radio method can be performed.

In the case of transmitting the analog signal of sound, a picture, etc., it is first modulated by an analog modulator 13 (AM, FM, or PM), sampled next by an analog pulse modulator 14 (PAM, PWM, or PPM), thereafter converted to an analog pulse string, digitized in synchronism with a reference clock signal, modulated by a digital modulator 19 corresponding to wireless, and transmitted.
