no ripple means butterworth, 4 db means this is HPF
fc=1/2pie RC=7957OHM
Apb =4
20logApb=4
Apb-1.585
Rf=Rapb=7957 x 1.585 =12.6kohm
Apb=1+Rf/Rs
1.585=1/(12.6k/Rs)
Rs=21.54kohm
i just know this few steps .if there any mistake
• No ripple can exist in the output, but non-linear phase shift is allowed.
• The frequency response must be as close as possible to the ideal filter response.
• Signals of frequency 0 ~ 5 KHz are only allowed to pass through the filter with a desired gain of 4dB . Other frequencies should...
a 3-to 6 binary decoder has an enable signal.When disabled or invalid code is applied to the decoder ,the decoder will output zeros.When enabled,input codes from 000 to 101 are decoded.Draw the block diagram of 3-to-6 decoder and define its behaviour using a truth table.
may i know how to do...
