A discrete time analog filter suitable for use in a receiver and other electronics devices is described herein. In one exemplary design, an apparatus may include a transconductance amplifier, a sampler, and a discrete time analog filter. The transconductance amplifier may amplify a voltage input signal and provide an analog signal. The sampler may sample the analog signal and provide analog samples at a sampling rate. The discrete time analog filter may filter the analog samples and provide filtered analog samples either at the sampling rate for a non-decimating filter or at an output rate that is lower than the sampling rate for a decimating filter. The discrete time analog filter may also filter the analog samples with either equal weights for a rectangular filter or at least two different weights for a weighted filter.
