In positive half cycle one diode is in forward biasing and other is in reverse biasing while in negative half cycle their polarity reverses, and direction of current is opposite through R for positive and negative half cycles so out put is not rectified.

Since R_{1} and R_{2}are different hence the peaks during positive half and negative half of the input signal will be different.
