Performing block reduction with many takeoff/summing points in sequence

I'm an audio programmer, and I've recently gotten into using transfer functions to model the response of my DSP. However, I've hit a roadblock in trying to reduce a block diagram of one of my DSP classes (specifically, a phaser), but I'm really…

What does "1/99 tap" mean in a block diagram?

I am still trying to understand the modulator in an optical free space transmitter. I have found the following block scheme: It is from "Direct-detection free-space laser transceiver test-bed". I am trying to make clear for me each part of this…

How to convert this transfer function in the z-domain?

I arrived at: $$\frac{Y[n]}{X[n]}=1-\frac{1}{6}z^{-2}+\frac{5}{6}z^{-1}$$ How do I arrive at: $$H(z)=\frac{1}{1-\frac{5}{6}z^{-1}+\frac{1}{6}z^{-2}}$$

Does every block diagram for an electrical circuit have a feedback loop

I was reviewing block diagrams on this tutorialspoint page and it showed how an RLC circuit is written with a feedback loop. It occurred to me that any time a block diagram of a circuit is created, there has to be a summing joint, hence there will…

Root Locus in a feedback loop

I'm trying to draw Root Locus by hand from the following block diagram and confirm the result I got from Routh Hurwitz's table: The table of Routh Hurwitz that I got is the following: And from the stability conditions I got K> 0. I calculate the…

Block diagram and operation of 16-bit output port for microprocessor-based system with specific requirements

A microprocessor-based system has an 8-bit data bus and a 10-bit address bus. It requires a 16-bit output port having two consecutive addresses starting from an even address. Furthermore, address needs to be configurable to any even address between…

Transfer function of cyclic block diagram

I have this block diagram, and I just can't arrive at the transfer function \$H(s) = \frac{y(s)}{u(s)} \$ Starting from the end, we see that $$y(s) = xC $$ Let's find out what x is. $$x=\Bigg[\bigg(u(s)-x\bigg)A-y(s) \Bigg]B $$ But as you can see…

What does this overlapping ADC symbol in a block diagram mean?

I am wondering what multiple overlapped ADC symbols in a block diagram mean. My best guess is that it either represents multiple channels but I am not sure and each of the datasheets that I have seen do not provide a clear answer as to what the…

How to design compensator for control system

I wanted to make this system so that there is zero steady-state error when there is a ramp input. As far as I know there is no steady-state error in a type 2 system so to turn G(s), a type 1 system to type 2 system I add an integrator (1/s) so that…
