Analog Signal Processing: A Time-Domain Demonstration of Microwave Differentiation

In this paper, the results of time-domain measurements for 1st, 2nd, 3rd, and 4th-order differentiators in microstrip coupled-line technology are presented for the first time. The proposed differentiators constitute an important tool for analog signal processing allowing us to perform a real-time derivative of the input signal of the desired order. Moreover, a time-domain setup suitable to verify the operation of analog signal processors (ASP) for ultra-wideband (UWB) signals is described in detail.
