X(+) 0 Spectrum of x₁ (t) 10 31 Spectrum of x₂ (1) 50 70 Spectrum of x3 (1) 90 I f[Hz] It is desired to pass the signal x₁ (t) by passing the sequence x(n) through a digital low pass IIR filter. Use the impulse invariance method to design Butterworth filter with the following specifications: maximum ripples allowed in the passband -0.3 and the maximum ripples allowed in the stopband =0.1.
