We propose a new rule, loop reversal, in block diagram and signal flow graph manipulation (or transformation) that leads to equivalent block diagrams or signal flow graphs from existing ones. It is ...

GRC uses a block diagram (a flow graph) to represent your project. When you create a new flow graph, you’ll see two blocks already present: one for options, and a variable named samp_rate.

Figure 1: Signal flow diagram in a first order Sigma Delta ADC. How a modulator works The working of a modulator can be explained using a conversion example. In Table 1 the headings X, B, C, D, and W ...
