Abstract :
A comparison of transmission and reflection all-pass phasers is conducted in terms of resolution for analogue signal processing. First, a formula for resolution is derived based on the fundamental operation of real-time Fourier transformation. Next, the condition for equal resolution of the two types of phasers is established as a general relation between their coupling coefficients. It is subsequently shown that reflection phasers impose less constraint on the coupling coefficient than transmission phasers.
