sorry to bother you all again but i have a small question i cannot do. it is
on analogue electronics, which i don't know if any of you can answer.
here it is, its only worth 6 marks.
an amplifier has a second order gain/frequency response with a lower cut-off
frequency of 350Hz, an upper cut-off frequency of 4kHz and a mid-band
voltage of 50 dB.
sketch the graph of gain against frequency.
estimate the voltage gain in dB at the following frequencies.
i) 20Hz
ii) 350Hz
iii) 2kHz
iv) 10kHz
