AB  - The techniques of flanging (signal + delayed signal) and processing with a phaser (signal + all-pass filtered signal) are discussed. The considerable differences between the results of the two techniques are noted. It is shown that in the limit of an infinite number of one-pole all-pass stages processing with a phaser can become equivalent to flanging. It is shown that for a finite number of stages a phaser is optimized if all stages have the same time constant. In that case the peaks and zeros of the transfer function are most uniformly distributed in frequency.
