3 Bar plot using plotnine Bar plot has a similar aim to the histogram. It lets us discover and show the underlying frequency distribution of a set of categorical data. As we know that categorical data can not be measured by the mathematics equation, such as multiplication, subtraction, etc b...
Design a digital lowpass filter such that the passband is within 3 dB up to 0.2*(fs/2), while rejecting at least -40 dB above 0.3*(fs/2). Plot its frequency response, showing the passband and stopband constraints in gray.相当于截止频率0.3*(fs/2)HZ,转换成0.2rad/s和0.3rad/s,就不用...
