This tech talk covers how the z-domain (or the z-plane) relates to the s-domain and the time and frequency domains. It also walks through why the z-plane is a polar plot and how the recursion coefficients are the same as z-domain transfer function coefficients.

Hi everyone, I'll be on and answering questions during the premiere. Feel free to drop any questions or comments here in the meantime and I'll try to get to them before then. Cheers!

I just found out about the Tech Talks with Brian and oh my... I've been BINGINGGGG on these videos. I just finished my EE degree and watching all these videos with amazing clear explanations have been doing wonders in bridging the gaps of my undergrad knowledge. Thank you so much for these gems, Brian! You da goat.

I really liked the domain map, that was really helpful for seeing how the frequency analysis techniques are connected. Also the z domain animation wrapping around the s domain was crazy. This video was great

I know z domain but hearing Brian's voice makes me happy😂 I already graduated from my master's but watching his videos reminds me if control theory lectures which were my fav of all.

Thank you Brian for the great explanation on Z-Domain. I am currently working on Data driven method for nonlinear systems using the Discrete Volterra Series; I didn't catch the relationship between this representation and the Z-Domain. I think now, I have a kind of better understanding. Keep up the good work !!

I’m currently studying DSP and this is really helpful. Thank you!

@user-xq6dq7xe5e Месяц назад

at last you have made a video on z-plane after z- transform and have given a reference/recommendation of another video also. May ALLAAH give you better reward

@sebastianarmstrong2775 Месяц назад

Thank you Brian for a thought-provoking video. The quirks and physical meaning of each domain (frequency, s, z, discrete frequency) felt like an undervalued topic during my undergrad. I have enjoyed your recent videos on this subject--especially the "map" relating the various domains and your intuitive explanation as to why the z-domain uses polar coordinates. I will be recommending this video to friends who have questions on the z-domain. Looking forward to your next video, and I hope you have a great day.

Hey that was fantastic, can't wait for the digital controller video, thanks 👍🏼

@BrianBDouglas Месяц назад

Thanks! A digital controller video would be a good follow up for this.

@Gowtham-tb5eg Месяц назад

Thank you sir, i got clarity on z transform

@BrianBDouglas Месяц назад

Great to hear 🙌

@BCarli1395 Месяц назад

Very helpful, thanks.

@abhijithas9976 Месяц назад

Thanks, i am looking for this type video , got good clarity,

@tim110-handle Месяц назад

yes finally!!

@ 12:24 impulse response should be discrete not continuous because time domain signal is discrete... that is ZT exists only for discrete-time signals

@hughferguson9142 Месяц назад

How can the Z transform help identify how different frequencies decay in a signal? What can it tell about a signal and how the frequencies change over time? Thank you!

@PankajSingh-dc2qp Месяц назад

@ 15:01 *integrator* example is also misleading. Integrator is actually a continuous-time device.... the discrete-time equivalent of integrator is *accumulator* that sums the number of samples... Integrator never takes a discrete-time signal as input, u[k] and gives discrete-time output, y[k] as shown in the video.... it works on continuous-time signals

@rhythmwinicour3914 Месяц назад

How does mapping from the s-domain to the z-domain affect the frequency response of a digital filter? Specifically near the Nyquist rate

@dominikz5776 Месяц назад

Plot z,s of the tustin transformation s=(2 (z-1))/((z+1) t_s)

@PankajSingh-dc2qp Месяц назад

z-domain is not discrete... it is continuous

@BrianBDouglas Месяц назад

Thanks for the clarification, my explanation is misleading. I should have just explained that the Z-domain is the discrete-time equivalent of the S-plane. But you are right, that the domain itself is continuous.

@bbhh-ud9zo Месяц назад

RIGHT! DTFT is continuous, while DFT is discrete.
