An electronic apparatus comprising a radio transmitter is disclosed. In a computer system () having a radio transmission circuit () of a phase modulation type supplied with power from a power supply () of a switching type, the switching frequency of the power supply () is determined based on the comparison frequency for the sampling operation of a PLL circuit () of the radio transmitter, thereby removing the power noises generated from the switching regulator of the radio transmitter of a phase modulation type.
