In a 4-channel data acquisition system, the input channels are selected sequentially using a multiplexer switch on each clock edge. If the inputs are A = 3 cos(2π × 8000t), B = 5 cos(2π × 4000t), and C = 6 sin(2π × 2000t), what is the minimum clock frequency required for proper sequential sampling of all inputs based on the Nyquist criterion?
