Abstract
A Direct VCO (DCO) modulation apparatus and method that provides a wideband modulated signal output. The wideband response is obtained via signal processing to counteract a high-pass frequency characteristic as seen from the VCO modulation input. That is, low frequency components of data signals are compensated before being applied to a VCO input. The high-pass characteristic in combination with the compensated signal provides a relatively flat, wideband frequency response of the DCO modulator.
