Direct RF Signal Measurements using Digital Signal Processing

InterSpace, Inc. proposes to design an instrument to directly measure Radio Frequency (RF) signal parameters using Digital Signal Processing (DSP) techniques. The proposed method will directly yield frequency and relative phase and amplitude measurements of broadband mutlispectral signals. Recent introductions of digitizers and processors, operating at GHz bandwidths have the potential to make this approach feasible. InterSpace, Inc. has developed several proprietary algorithms that can instantaneously measure closely spaced frequencies. These techniques have the advantage of low latency measurements useful for tracking signals and measuring signal jitter.
