Ok I will put it this way. In my FPGA I have two logic blocks, one is ADC control logic block and another is the control algorithm. Both these blocks have clock as its inputs. Since my aim is synchronous design, I need to connect the same clock to both the models. So whatever clock I choose, I...
The issue is that I need to fetch 4 data inputs from ADC. According to data sheet we need to pulse the RD 4 times in order to fetch. If I use the same very 10KHz clock source, then for pulsing RD , it will consume 4 clock cycles(min), then the data will be available to the control model only...
I have a control system modeled in matlab, which takes the inputs from ADC and then continues to process the data. Simulation works fine. In real world,I am not sure how to fix the sampling rate. ADC is a simultaneous sampling type (AD7606) and the fixed point algorithm runs in FPGA. I am using...
I was browsing about legacy game console emulator of amiga/atari systems. I was wondering the process by which they emulate the wiring between CPU, memory and peripherals such as keyboard and so on to work in real time. How does address decoding work , when there is no real hardware. I just...
Yes, Yes, the recursive feature makes IIR to generate infinite impulse response, whereas in FIR , it is limited due to finite coefficients (without feedback)
OK, I get it. Confusion arose because, If we were to provide just the unit impulse to a system ( such as RC), eventually output would decay within certain time. In other words, the response to a unit impulse will be finite . Now I wanted to map this very concept with the definition of FIR and...
I have seen several materials on the net. Yet I could not conclude the true meaning of IIR and FIR. Impulse responses will remain always remain infinite for Infinite inputs, which goes forever. Only coefficients could decide the distinction
By reading the posts above, should I conclude that FIR and IIR is simply dependent on the coefficients that define the filter. FIR has finite coefficients and IIR has infinite
I am new to digital filters and have a very basic question about IIR and FIR filters. I would like to know the essence and basis of these filters. There are tons of literature on web that details the design of these filters without directly providing the genesis. One fundamental question is that...
I want help regarding the design of harmonic filter (PCB mount) that shall tolerate THD of 25% (max). Also required to design low pass filter to eliminate high frequency components (1KHz and higher). Incoming signal is 10V/50Hz. Total group delay of the filter network shall not exceed 100us. Is...
Ok, it is partially clear. I wanted to understand the reason for summation in the equation of convolution. Summation alters the entire distribution. OR can we take it as the same consequence of multiplying two polynomials, which results in multiplication and addition
As you know that analogies or examples are incomplete as they do have corner cases. But please explain the role of convolution. When to decide that we need convolution to solve a problem.
This is an elementary question on signal processing with analogy. To increase the quantity of anything, we may use either add or mul operator. Similarly, to reduce a quantity of something we can use either subtraction or division. Now what is the corresponding function or attribute we are...
