''A machineoutputs a 4kHz sine wave signal of amplitude 2 volts peak, plus a 100Hz interference component of amplitude 1 V peak''

Given equation: Vout/Vin = 1/((1+(f0/f^2))^0.5 phase lead = inverse tan (f0/f)

f0 = 1/(2*pi*R*C)

I'm given a 4 kilo-ohm resistor and need to choose a capacitor to reduce the interference (100 Hz signal) to 0.05 V peak; I need to design a high pass RC circuit.
