Time delays are often encountered in engineering systems. They can be approximated using Euler’s definition as


If T = 1 and N = 1, then the approximation can be implemented by the circuit of Problem 8.17 (see Figure P8.17), with the addition of a unity gain inverting amplifier to eliminate the negative sign. Modify the circuit of Figure P8.17 as needed, and use it as many times as necessary to design an approximate time delay for T = 1 and N = 4 in Euler’s definition of the exponential.
