What are the drawbacks of Direct Conversion Receivers? DC offset is coming from local oscillator leakage. The local oscillator leakage problem causes a large DC offset in the baseband and saturates the baseband circuits. Read more. LO Leakage – Direct …
What is a Homodyne Receiver? In a receiver the frequency of a signal is shifted by multiplying with another sinusoidal signal called the carrier wave. This multiplication is performed by a mixer and the sinusoidal wave is generated by the …
How is the Structure of Heterodyne Receiver? Till now we have discussed on various structures for heterodyne receivers and the image problem faced by the receiver. The first simple structure discussed is shown in figure 1. Read about the heterodyne …
