I have a scenario where 𝑥(𝑡)=2⋅sin150𝜋t +sin250𝜋t and g(t)=𝑥(𝑡)sin250𝜋 . The signal g(t) is passed as input through an ideal lowpass filter with cutoff frequency(fc)= 300𝜋 and passband gain= 3.
what will be the output signal of the lowpass filter? Please suggest if there is any formula or representation to calculate this?
I know the ideal function of a Low Pass filter is meant to block all high range frequencies and allow low frequencies. Can anyone suggest any formula to evaluate this?
I am new to this concept of filtering .
