Demonstration 1: Sampling 

His synthesis power, his ability to process such a complex subject in order to make it clear for someone new on the matter, is simply superb. Hands down one of the best teachers ever.

My greatest achievement in my life thus far is being able to truthfully say that I understand everything that this man is saying

Love the use of ragtime for the audio demo. That make me smile.

This lecture brought back horrible memories of stats classes!

00:00 使用可编程数字滤波器演示采样和混叠效果 03:57 如果带宽与采样频率相比太大，则对带限信号进行采样可能会导致混叠。 07:51 增加输入频率会导致输出频率增加，直到出现混叠 11:06 使用非理想低通滤波器观察混叠效应 14:25 可以使用频率响应找到等效的连续时间系统 18:01 重新调整数字滤波器中的频率轴 21:21 滤波器频率响应和改变采样频率的影响的演示 24:38 通过改变采样频率来改变滤波器截止频率的演示 Crafted by Merlin AI.

Buffer is a logic gate that produces output identical to Input but with a delay. This concept can help us design an artificial memory access unit similar to that of natural memory access unit present in human brain. My intuition says that in Alzheimer's disease the memory does not gets affected, rather the Memory Access unit gets affected... The job of memory access unit in brain is to give output same as input but with a delay and this is what the buffer does...generally the signals present in nature are analog but we can use analog to digital converter and digital to analog converter in designing artificial memory access unit... We can easily find Transfer Function (while dealing with analog signals) of memory access unit where we want output same as input but with a delay...Anyone who is genuinely interested in helping the Alzheimer's patient will surely find this comment useful and will strive to help humanity deal with this disease...

Nice lectures, although the intro is a bit creepy!

Really think this course needs an update.

oh the seventies, long hair, porno mustache. Miss it very much.

good point!

Was so difficult to filter those annoying high frequencies of this video?

thank you sir

奥本海姆，你是我爹

Thank you!

The intro/outro music is creepy

too advanced
